What is sustainable jewelry?

Jewelery is sustainable if it consists of, among other things, sustainable materials.

The metals used are then recycled or fair trade. The precious stones used in sustainable jewelry are also fairly traded, certified and traceable or grown directly in the laboratory.

As far as possible, neither plastic nor animal products such as pearls, mother-of-pearl, horn or similar are used for the jewelry and its packaging. In addition, with sustainable jewelry, care should be taken to ensure fair production, which is best done locally with fair wages for the workers and safe working standards.

In addition, sustainable jewelery is characterized by high quality, a timeless design and high-quality materials so that it can be worn for as long as possible.

This saves resources, less is disposed of and less is produced.

What makes Maren Jewelery sustainable?

At Maren Jewelery we follow a holistic approach to sustainability.

We want to design jewelry in harmony with nature. Therefore, we only use sustainable materials such as recycled metals and laboratory-grown diamonds and produce our jewelry locally in Germany and made to order. This allows us to avoid long transport routes, unnecessary storage and overproduction. .

Each of our pieces of jewelry is fully recyclable, with which we are striving for a circular economy in the long term. We value fair working conditions and only work with suppliers and partners who share our sustainable vision of jewelry production. Transparency is very important to us in all respects.

Our pieces of jewelry are all high-quality, durable and minimalistic, carefully handcrafted.

The packaging also makes our jewelery sustainable. We do not use plastic or animal products.

With the sale of our jewelry, we also support the sustainable initiative Chooose and offset 100kg of CO2 for each piece of jewelry produced.

Which sustainable initiatives does Maren Jewelery support?

Maren Jewelery has decided to support two initiatives in the long term in order to produce each piece of jewelery in the best possible way in harmony with nature:


Although each of our pieces of jewelery uses 0.4 kg of CO2 on average, around 73 times less CO2 than the average piece of jewelery produced, every time we sell one of our pieces of jewelery we offset 100 kg of CO2 with a donation to the sustainable initiative Chooose in order to be climate-positive.

More info

Earthbeat Foundation

At Maren Jewelery we only use recycled materials so that we don't have to mine more gold and use what is already there. However, in order to do something for positive change in the gold industry and for the nature and people of the mining areas for which we want to take responsibility, we support the Earthbeat Foundation with 3% of our annual profit.

TheEarthbeat Foundationstands up for people whose livelihood is mine work due to a lack of alternatives. New sustainable sources of income are being created locally by the Earthbeat Foundation, such as the beekeeping project.

More info

What does climate positive mean?

Climate positivity exists when more greenhouse gases are offset than were caused. This is positive because, according to the Paris Climate Agreement, the progressing global warming can only be stopped if significantly more CO2 is saved.

Thanks to our holistic approach to sustainability, the consumption of our jewelery at Maren Jewelery is negligible, with approx. 0.4 kg of CO2 per piece of jewelery produced, compared to conventional luxury jewellery. These consume around 73 times as much CO2 on average.

However, that is not enough for us and we offset 100kg of CO2 with every purchase of a piece of jewelery with donations to the Chooose initiative. Since that is significantly more than the 0.4kg CO2 consumed, Maren Jewelery is climate-positive.

What is a sustainability report?

In a sustainability report, organizations take up the achievements and initiatives that they have made in the context of sustainability, especially in relation to the topics of economy, ecology and social affairs, and draw a summary.

In addition to the annual report, it is an important information tool for companies to report annually on the sustainable development progress of the organization and to inform interested parties about the sustainable orientation.

To our sustainability report

Does Maren Jewelery have a sustainability report?

Yes, although it is not mandatory for Maren Jewelery to file a sustainability report, we have decided to inform you about our sustainability activities and initiatives in a comprehensive report and to disclose our figures.

Because transparency is important to us. With the help of our sustainability report, we want to give you and ourselves a unit of measurement. We want to know where we stand in order to show where we want to go. That's why you can use the sustainability report to get an accurate picture of how much Co2 our jewelry consumes compared to conventional jewelry, where we source our synthetic diamonds, our recycled gold and silver and who produces it for us.

You will get a detailed overview of our holistically sustainable supply chain and our values ​​and goals. In this way you can assure yourself that our holistic understanding of sustainability is important to us and that these are not just empty phrases.

To the sustainability report

Is sustainability reporting repeated at regular intervals?

Yes, every year in July we create a new sustainability report for you and us to re-evaluate our initiatives and activities and to make us aware of successes, weaknesses and potential.

In our opinion, growth in the sense of understanding is only possible if we deal openly with weaknesses.

Only if we are regularly aware of where our weaknesses lie can we respond appropriately and improve. Not only for us, but above all for nature. And we want to make this possible with regular sustainability reporting. Because that too is mindfulness for us. Maren Jewelery is not a closed, finished company, but dynamic. We want to move, want to grow and learn.

We want to challenge ourselves. We have goals, like the circular economy, that we want to achieve.

Why is minimalist jewelry sustainable?

The sustainability of jewelry is also about the jewelry being as durable as possible, pleasing for a long time and not going out of fashion so quickly.

Minimalist jewelry is sustainable because it is timeless, doesn't follow any trends, can be combined with anything and can therefore be worn for a particularly long time.

In addition, minimalist jewelry saves resources. Because everything that is superfluous is dispensed with.

When we create our simple designs at Maren Jewellery, we therefore focus on what exactly we want to say with each piece of jewelry and only use as much recycled gold, as much silver and as many synthetic eco diamonds as necessary. This not only leads to a clear, unexcited design language, it also ensures that we minimize our consumption of resources.

This is why minimalist jewelry is sustainable because it focuses on the essentials and leaves out everything else.

Recycled Gold

What Are the Benefits of Recycled Gold?

Recycling gold avoids the mining and consumption of new, finite resources, because there is already enough gold in many production waste or old throwaway goods to prepare it for reuse.

Since gold can be melted down and reused again and again without loss, recycling gold is an environmentally friendly and also humane alternative.

Because gold mining is not only dangerous and harmful to the health of all mine workers, but unfortunately it is also often practiced by children and heavily pollutes our water, soil and air through the use of cyanide and mercury.

TheWWF, as well as theAssociation Save the Rainforest considers recycling gold to be the most sustainable form of gold extraction and processing. It uses 550 times less CO2 and 8.9 times less water than with newly mined gold. In addition, recycling gold can prevent tons of toxic mine waste from ending up in our water, mine populations from being displaced, or forests that are important for our biodiversity from being cut down.

Since 48.6% of the gold demand can be traced back to demands from the jewelery industry, a considerable difference can be made by choosing recycled gold: just imagine all jewelery manufacturers* using recycled gold.

More info

What does the gold recycling process at Maren Jewelery look like?

For the recycled gold that we use in our jewelry at Maren Jewellery, we work closely with our partner, theRefinery C.Hafnertogether who carries out the gold recycling process for us.

We hand over all our valuable, collected gold residues, which have arisen from castings, filing waste or polishing dust, to C.Hafner so that they can be melted down with other scraps. For this purpose, the scrap is first weighed and then melted down so that the precious metal is homogenized and then cast into ingots.

Samples are then taken from these bars and quartered with lead. The lead absorbs the precious metals in the crucible and then evaporates in the heat. What remains is the precious metal grain. This grain is then hammered and rolled. Only now does the actual separation process of separating or cutting the precious metals begin. The debris dissolves in aqua regia. There, the various precious metals contained in the scrap are separated from one another and can be recovered in their pure form: palladium, platinum and also gold.

At the end of the gold sheathing process is pure gold sponge. This is melted down and granulated and the result is impressive: recycled fine gold with 99.99 percent purity.

More info

Isn't new gold mined for Maren Jewelery?

No, at Maren Jewelery we only use recycled gold, so no new gold needs to be mined for our jewelry.

We receive the recycled gold from our RJC certified Refinery C.Hafner, which extracts gold from old jewelry, electronics or gold from dental technology and fuses it into a new, recycled gold alloy. The materials for this come 90% from Germany and 10% from the neighboring EU countries.

Also ours Foundry Kauselmannworks exclusively with recycled gold and thus prevents new gold mining.

What is urban mining and how can it be used to mine gold?

Urban mining describes the process of preparing raw materials that have already been extracted and used in goods that are no longer required, such as old smartphones or vehicles, and bringing them back into the material cycle. Urban agglomerations are viewed as huge raw material depots, since huge amounts of electronic waste accumulate there every year, and the extraction of new resources can be spared by recovering the raw materials.

This also applies to gold mining, because the gold used in old PCs, vehicles or smartphones can be extracted and recycled.

Urban mining thus prevents new gold mining and makes sustainable recycled gold possible.

More info

What are alloys and which gold alloys are there?

Since pure gold is too soft for jewelry processing, it is fused with other metals such as silver, copper or palladium for jewelry production. This fusion of gold with other metals in different mixing ratios is called a gold alloy.

The best-known alloys are 8 karat (also 330 gold), 14 karat (also 550 gold) or 18 karat (also 750 gold).

The 18 carat gold has the highest gold content with 75%.

In terms of color, a distinction is made between yellow gold, rose gold, red gold and white gold alloys. The different colors are caused by the different mixing ratios of the metals.

Which gold alloy does Maren Jewelery work with?

For the gold alloy, we at Maren Jewelery have decided to use only recycled 18k yellow gold and 18k white gold in order to produce high-quality, long-lasting pieces of jewelery for you.

Both of the gold alloys we use are 75% pure recycled gold.

The difference in the colors is caused by the different mixing ratios.

Our recycled yellow gold is composed of 75% pure gold, 15% silver and 10% copper.

The recycled white gold consists of 75% pure gold, 4% silver, 7% copper and 14% palladium (a platinum metal).

Is 750 gold and 18k gold the same?

Both the specification 18 carat and the designation 750 gold indicate the total proportion of pure gold within a gold alloy, i.e. the fusion of different metals.

The karat specification for gold is a unit of measurement for the proportion by weight that the pure gold occupies in the overall mixture of the alloy, also known as the fineness.

The fineness is given in 1/24 parts. The largest possible weight percentage of pure gold within a gold alloy would be 24/24 weight percentages, i.e. 24 carats.

However, the fineness of gold can also be stated in percent by weight. 18 carats then correspond to exactly 75% gold in the total mass of the alloy at the highest possible 24 carat fineness.

The designation 750 gold, based on the 75% gold content, therefore describes the same purity of the alloy and can be used synonymously.

What is the quality of 18k gold?

The 18 carat specification for gold is a unit of measurement for the proportion by weight that gold occupies in the overall mixture of an alloy.

The weight percentage (also fineness) of gold is given in 1/24 parts. The highest purity of gold, i.e. the highest proportion of pure gold by weight within a gold alloy, is achieved at 24/24 parts by weight, i.e. 24 carats. However, since possible impurities can never be completely eliminated, even 24-carat gold only achieves a purity of 99.99%.

However, 24 carat gold is not suitable for processing jewellery, as it is much too soft and bends easily.

Therefore, 18 carat or also called 750 gold with 75% gold content is the highest quality gold alloy that is suitable for processing jewelry.

Recycled jewelry vs. fair jewelry - what's the difference?

With fair jewelry, i.e. jewelry made with fair trade metal and gemstones, attention is paid to fair working conditions with fair payment and strict environmental and humane regulations when mining gold and stones.

Fair jewelry therefore minimizes the damage to the environment considerably. In addition, prospectors in fair trade mines are continuously taking action against the abuses of the industry, which is extremely worthy of support. But fair trade jewelry is also made from newly mined metals that pollute our environment.

Recycled jewelry avoids this problem, because the use of recycled metals does not cause any further damage to people or nature and resources are used that are already available in abundance.

The recycling process is particularly productive for pieces of jewelery made of gold, because gold does not lose any of its purity or quality when it is melted down, which makes it ideal for a circular economy.

Why doesn't Maren Jewelery use fair trade gold?

Fair Trade Gold is promoted under fair working conditions, with fair pay and under strict regulations that promote the protection of people and the environment.

This is of course a very positive step forward compared to traditional degradation standards.

The fact that prospectors in fair trade mines are taking concrete action against abuses in the industry with new standards and environmentally and humane regulations is also extremely worthy of support.

But fair trade gold is also newly mined gold that causes avoidable damage to our environment and for which miners are exposed to a major health risk.

That's why we at Maren Jewelery have decided to only use recycled gold for our jewelry instead of fair trade gold.

Recycled Silver

What Are the Benefits of Recycled Silver?

Just like with recycling gold, recycling silver also prevents the mining and consumption of new, finite resources.

Silver is also found in many production waste or goods that are no longer needed and can be recycled from it for reuse. Silver can also be melted down without loss, so recycling silver is a sustainable method of protecting people and the environment and using what is already there.

Since silver is usually mined together with gold in mines, the advantages of recycling silver are obvious: mine workers do not have to expose themselves to life-threatening or health-damaging risks and our environment is protected.

The recycling process of silver uses 7-14 times less CO2 than with newly mined silver.

In addition, recycling silver can also prevent tons of toxic mine waste from entering our water, populations being displaced due to mine construction or forests that are important for our biodiversity being cut down.

How is Maren Jewelery's 925 sterling silver recycled?

Our partner, the Refinery C Hafnerobtained with the help of a silver recycling process.

Just like with gold, we constantly collect all our silver residues that arise during the production of our jewelry by polishing, filing or casting and hand them over to C Hafner so that they can be melted down with other scraps to 925 sterling silver.

For this purpose, the material to be cut is also melted down here until it is homogenized and can be cast into ingots. Samples are then taken from these bars and quartered with lead. The lead absorbs the precious metals in the crucible, only to be volatilized in the heat, leaving the precious metal grain behind.

This grain is then hammered and rolled and dissolved in aqua regia so that it can be separated from other precious metals and processed into our jewelry as recycled 925 sterling silver.

Is sterling silver real silver?

Sterling silver is a fusion, also called an alloy, of 92.5% pure, real silver and 7.5% copper. It therefore has a silver purity of 92.5%, which is why it is also called 925 silver. Since silver is very soft at 100% purity, it is not suitable for making jewelry. Therefore, sterling silver is the highest quality silver alloy used in jewelry production.

What is the quality of 925 sterling silver?

Sterling silver, also known as 925 silver, is composed of 92.5% pure silver and 7.5% copper. It has a fineness of 92.5%.

Because alloys with a higher silver content lose stability, 925 sterling silver is the highest quality silver used in jewelry making.

Synthetic Eco Diamonds

What are synthetic diamonds?

Synthetic diamonds are diamonds grown in a laboratory.

They are identical to natural diamonds in terms of appearance, hardness and chemical composition.

The advantage of synthetic diamonds, however, lies in their sustainable and humane extraction, as this neither pollutes our environment nor puts people in crisis areas at risk.

There are two techniques for producing synthetic diamonds: the CVD process and the HTHP process.

At the Chemical Vapor Disposition (CVD) Diamonds are created in a plasma that is as hot as a small sun on Earth. Our partner Fenix ​​Diamond uses this technique. Diamond Foundry also grows using the CVD process and produces novel plasma reactors that generate such heat that atoms attach to the natural diamond crystal lattice of a diamond, which is used as a basis in this process. In this process, more and more atoms are stacked on a thin diamond foundation, thus expanding the unique crystal structure of the seed diamond. Atom by atom, a pure, decorative synthetic rough diamond grows into the size of a gemstone.

HTHP stands for High temperature, high pressure. In this process, which is based on the natural formation process of diamonds, graphite-2H is placed in growth cells, which are subjected to pressure of up to 70,000 bar on three sides in so-called cubic presses. Graphite-2H is a natural form of the chemical element carbon, which has a hexagonal crystal structure similar to a honeycomb. The inside of the growth cell is first equipped with catalysts and seed diamonds and heated to around 1600-1700 degrees Celsius. Under these conditions, the graphite changes in a physical-chemical process and the black powder grows into a transparent diamond. Our partner Swiss Diamond Vision uses the HPHT process to produce lab-grown synthetic Eco Diamonds.

More info

Are artificial lab grown diamonds sustainable?

The process of growing diamonds synthetically in the laboratory ensures that no people in crisis areas were endangered in order to extract the diamonds.

Although laboratory-grown diamonds are just as pure and unique as natural diamonds, their origin is 100% guaranteed:

Our synthetic diamonds that we use for Maren Jewelery come from Switzerland, India or America. All of our gemstones are 100% conflict-free.

In addition, diamonds grown in the laboratory are resource-efficient. If 1ct diamond is mined in the traditional way, up to 200 tons of earth have to be moved. Moving these masses requires an incredible amount of energy.

Our synthetic diamonds are much more environmentally friendly than natural diamonds.

They consume 4,79,19 times less CO2 than normal diamonds. The high energy required for the breeding process is also problematic, but this is taken into account by our partner Diamond Foundry, which, like Maren Jewellery, is a CO2-neutral company..

Where do Maren Jewelery Eco synthetic diamonds come from?

At Maren Jewelery, we source our eco synthetic diamonds from three different, highly valued partners who share our vision of a sustainable, responsible use of our earth.

Our jewelry is therefore made from synthetic diamonds Diamond Foundry, which grows synthetic diamonds in the USA using the Eco CVD process, Fenix ​​Diamonds, which grows traceable laboratory diamonds in its solar-powered production in India and synthetic diamonds Swiss Diamond Vision manufactured. These were grown in the laboratory in Switzerland using the HTHP technique.

What are the 4Cs?

To assess the quality and authenticity of diamonds, four quality characteristics are considered, which are also called the 4 C's:

Carat (carat): Indicates the weight of the diamond. One carat is equal to 0.2 grams or 100 points.

Color (color): Indicates the tint of the diamond in gradations from D = colorless to Z = clear tint.

CLarity (purity): Determines the extent of peculiarities in the crystallization (inclusions) in three levels IF=flawless, VS=very small inclusions and SI=small inclusions.

Cut (cut): Evaluates the craftsmanship of a suitable cut shape.

Synthetic diamonds that were grown in the laboratory are also classified based on the 4 C's.

At Maren Jewellery, all diamonds have the color DG = colorless to almost colorless, a purity of vvs-vs, i.e. only very small inclusions and the cut quality is "very good" to excellent. From a carat weight of more than 0.5, all of our diamonds are Diamonds delivered with an official diamond certificate. . 

engagement rings

What is a sustainable engagement ring?

A sustainable engagement ring is a symbolic ring made from sustainable fair trade or recycled metals under mindful and responsible standards and is of high, durable quality.

If set with gemstones, they should be fair trade, certified and traceable, or grown directly in the lab.

In addition, it should have been produced under fair and humane conditions.

Since jewelery is always handmade, it can be assumed that either children are employed or workers are not well paid if the prices are cheap. Therefore, it is very important to get detailed information about the production.

Sustainable companies will answer every question openly and transparently.

What should I look out for when buying a diamond engagement ring?

An engagement is a very emotional and personal moment of love, which the engagement ring symbolically captures for eternity.

It is therefore important to many when choosing an engagement ring that it does justice to the preciousness of the moment and love and they are looking for a ring with precious stones. It is important to ensure that the gemstones in the engagement ring are fairly traded, certified and traceable or artificially grown in a laboratory.

From a size of 0.5 carats, the diamond should come with an official certificate, as is the case with the synthetic diamonds at Maren Jewellery.

In addition, the gemstones should be evaluated using the 4 C's to determine the quality of the stones and thus of the entire piece of jewellery.

How do I find out the ring size for an engagement ring?

The easiest way to find out the ring size for an engagement ring is to already have a ring from your partner as a guide that fits him or her well on the finger in question.

On every Maren Jewelery product page you will find ours next to the size selection fieldSize guide to download or print out, on which you can simply compare the ring with our circle patterns and thus determine the required size. The sizes shown correspond to the inner circumference of the ring.

If you don't have a ring that fits you, you can find out the ring size by cutting our measuring tape from the size guide and notching on the dotted line. Now all you have to do is put the measuring tape around your partner's finger and read off the ideal ring size.

To the size guide

Is it safe to order an engagement ring online?

In itself, it is harmless to order engagement rings or other high-quality goods online if you do this from trusted sellers.

Therefore, when buying online, always make sure that you can understand where the piece of jewelery and, if applicable, the diamond in your ring come from. Reputable dealers look forward to hearing from you, can always answer your questions transparently and are happy to share any information with you in order to give you the best possible advice on your online purchase.

A particular advantage of buying your engagement ring online is the fact that you can get a thorough overview of the information and details that are important to you, regardless of shop opening hours.

And if you are still not satisfied with your choice, you can always make use of your 2-week right of return.

wedding rings

Are wedding rings made of gold also sustainable?

Wedding rings are a sign of mutual love, so why shouldn't they also be a symbol of love for our planet?

Sustainable wedding rings made of recycled or fair-trade gold thus combine two advantages: they can remind us of a special person, a special day and give us a common strength, and at the same time they can make us think of the beauty of our planet with a clear conscience, in which ours is love takes place.

At Maren Jewelery we find the most beautiful and original form of love on the finger. We therefore have wedding rings such as theBold Essential Ring orEssential ringdesigned from recycled yellow gold or white gold, which are not only beautiful, elegant wedding bands, but are also made sustainably in harmony with our nature.

More info

Sustainable wedding rings:what should I look out for when buying one?

Wedding rings are the most symbolic and emotionally important piece of jewelry in the life of many couples.

Wedding rings are not only meant to last a lifetime, but also to please a lifetime.

In addition, it is important to many couples that the symbols of love worn on the finger were produced in harmony with people and nature and can be worn with a clear conscience. Then the choice falls on sustainable wedding rings.

In order to ensure sustainability when buying wedding rings, you should pay attention to a few criteria when making your selection. The rings should be made of high-quality, sustainable materials such as recycled metals or fair trade metals and have a high-quality finish. Attention should be paid to a simple, timeless design that can be worn for a long time and does not go out of style.

Another important factor is production. Sustainable wedding rings should be produced as locally as possible under fair working conditions and with fair wages. Since jewelery is always handmade, it can be assumed that either children are employed or workers are not well paid if the prices are cheap.

Therefore, it is very important to get detailed information about the production. Sustainable companies will answer every question openly and transparently. .

Are Maren Jewelery wedding rings also made of recycled gold?

Yes, at Maren Jewelery all pieces of jewelery made of gold are made of recycled gold, including our wedding rings.

More info


Under what conditions does Maren Jewelery produce?

At Maren Jewelery, we follow a mindful, sustainable and responsible corporate approach that defines each of our decisions and also permeates our entire production process.

Our pieces of jewelery are therefore made in the interests of our environment without compromise, from the initial design idea to the finished delivery to our customers.

We only use recycled gold, silver and synthetic eco diamonds as well as plastic-free packaging and only work with selected, sustainable partners and suppliers who share our vision and inspire us to think further about sustainability every day.

We advocate long-term relationships with our partners, support fair working conditions and strictly reject child labor.

Maren Jewelery exclusively produces Made to Order in Germany, which enables us to keep our transport routes as short as possible and to avoid overproduction. .

As far as we can, we do not use plastic in the manufacture of our jewelry.

More info

Is the jewelry from Maren Jewelery made in Germany?

Yes, 99% of the jewelery production for Maren Jewelery is made in Germany.

We only get our ear studs and earring backs from the USA, because we could only find a company there that sells certified, recycled earring backs that meet our sustainability standards. 1% of the components of our jewelry are therefore manufactured in the USA.

What is"made-to-order"and"manufacture to order"?

Maren Jewelery is Made For You. .

That means we don't make it until you order it. In this way, valuable resources are conserved, we avoid overproduction and unnecessary storage, and each piece of jewelery becomes unique. Because we passionately handcraft it to order for you, so that it stands the test of time:

Highest quality turns our jewelry into lifelong companions Made in Germany..

Is Maren Jewelery handmade?

Every piece of jewelery is carefully designed, manufactured and finally packed by hand at Maren Jewellery.

Each piece of jewelery therefore receives its own attention during our work and thus becomes a very individual one-off in our studio and in the workshops of our partners.

By the time the jewelry from Maren Jewelery reaches you, a lot of care and love has gone into the production of your very own unique piece.

What is circular economy?

A circular economy is a process model in which the life cycle of materials and products is extended and extended as long as possible, so that new resources are saved.

This is done by using goods for as long and as often as possible and maintaining their functionality. If this is no longer possible, they are recycled at the end of their life cycle and reused to create new goods.

This idea makes it possible to let materials, once mined and manufactured, flow into a cycle of reuse and to avoid the mining of new resources as much as possible.

More info

What does a circular economy look like in jewelry production?

So far, there are hardly any jewelry companies that rely on a circular economy in jewelry production.

We at Maren Jewelery want to change that, because the metals used in jewelry can be melted down again and again without loss of purity.

That's why at Maren Jewelery we only use high-quality, reusable materials such as recycled metals, which on the one hand are easy to repair and on the other hand can be melted down again and again.

Since we already focus on this in the design, all of our pieces of jewelry areDesigned for Deconstruction. This means that you can always disassemble them back into their individual parts, melt them down and recycle them.

In the long term, it is therefore our goal to offer the return of all pieces of jewelry in order to manufacture new pieces of jewelry from the materials according to the wishes of our customers. This would enable us internally to let the resources we use flow into a waste-free cycle, ensure circularity and avoid unnecessary waste production.

In order to keep the piece of jewelry for as long as possible, we of course offer repairs and refurbishments at any time.

jewelry care

What is the best jewelry care?

Of course, the best jewelry care always depends on the specific piece of jewelry you want to care for.

Sometimes gold jewelry needs different care than silver jewelry or diamonds. The bottom line is that if you love your jewelry, you should show it with the right jewelry care.

Polish it, give it a soapy bath and a tidy jewelry box. Then you can not only enjoy your jewelry for a long time, but it will also last longer. This is also an aspect of sustainability.

Because when we take care of what we already have and nurture it as best we can, we need to consume fewer new things and do our planet a favour.

How do I care for my gold jewelry?

The care of 18 carat gold jewellery, as we exclusively produce it at Maren Jewellery, is very easy due to its purity and the resulting very resistant material.

Gold jewelery is easy to clean and care for and is therefore particularly durable.

If your gold jewelry is fading, you should put it in a lukewarm bath with soap, give the soap a moment to take care of your jewelry in the water, then you can take it out of the bath and gently rub it with a soft toothbrush.

Then you can simply dry your rings, earrings or bracelets with a soft cloth and they will look neat and shiny again, just like before.

More info

How do I care for my silver jewelry?

Caring for silver jewelry is easy if you follow a few tips.

Maybe something fundamental first: why does silver jewelry oxidize on silver at all? This describes the reaction of silver jewelery with oxygen. The oxidation causes the jewelry to tarnish and appear dirty. This is a completely natural process that is not bad at first.

However, because oxygen will tarnish your silver jewelry, it's best to store it in an airtight manner. Jewelry boxes or something similar are suitable for this.

And if your silver jewelery does tarnish, you can easily clean the tarnished areas with a silver cleaning cloth and thus restore your piece of jewelery to its former glory.

Does water stain sterling silver or gold or is it waterproof?

Sterling silver or 925 silver is solid silver just like our 18 carat gold, which is waterproof due to its high fineness and does not discolour through contact with water.

However, sterling silver can react with oxygen and oxidize. The oxidation causes the jewelry to darken and appear dirty. This is a completely natural process that is not bad. Because tarnishing can be minimized by storing it in airtight containers.

Should it happen, you can easily clean out the tarnished areas with a silver cleaning cloth or a silver bath.

How do I care for my diamond jewellery?

Diamond jewelery and therefore also our synthetic eco diamonds need the right care in order to be able to maintain their shine over the long term.

Because even if the diamond is one of the hardest materials, it can suffer a lot of damage if it is not cared for properly. For example, when diamond jewelery is exposed to large temperature changes or when it comes into contact with perfume, cosmetics or household chemicals. But that doesn't happen if you consciously take care of your diamond jewelry and take good care of it. And it's not that difficult: All you need is some lukewarm water, a bit of soap and a soft cloth.

If you treat your favorite piece carefully with it on a regular basis, it will last a lifetime.
