Jewelry is sustainable if it is made of sustainable materials, among other things. The metals used are then recycled or fair trade. The gemstones used in sustainable jewelry are also fair trade, certified and traceable or grown directly in the laboratory. If possible, neither plastic nor animal products such as pearls, mother of pearl, horn or similar are processed for the jewelry and its packaging. In addition, sustainable jewelry should pay attention to fair production, which is best done locally with fair pay for workers* and safe labor standards. In addition, sustainable jewelry is characterized by high quality, 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.

At Maren Jewellery, we take 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 lab-grown diamonds, and produce our jewelry locally in Germany and 'Made to Order'. This way we avoid long transport routes, unnecessary storage and overproduction. Each of our jewelry pieces is completely recyclable, which is how we strive for a circular economy in the long run. We value fair working conditions and work exclusively with suppliers and partners who share our sustainable vision of jewelry production. Transparency is very important to us in all aspects. Our jewelry is all high quality, durable and minimalist designed with careful craftsmanship. Even the packaging makes our jewelry 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 per piece of jewelry produced.

Maren Jewellery has chosen to strongly support two initiatives in order to produce each piece of jewelry in the best possible way in harmony with nature:


Although each of our jewelry pieces consumes an average of 0.4kg of CO2, which is about 73 times less CO2 than average manufactured jewelry, we offset 100kg of CO2 each time we sell one of our jewelry pieces with a donation to the sustainable initiative Chooose to be climate positive.

Earthbeat Foundation

At Maren Jewellery we only use recycled materials to avoid mining more gold and to use what is already there. Nevertheless, 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.

Die Earthbeat Foundation is committed to helping people whose livelihood is based on mining for lack of alternatives. Locally, the Earthbeat Foundation creates new sustainable sources of income, such as the beekeeping project.

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

Due to our holistic approach to sustainability, the consumption of our jewelry pieces at Maren Jewellery is vanishingly small compared to conventional luxury jewelry, at about 0.4 kg of CO2 per piece produced. The latter consume on average about 73 times as much CO2. Nevertheless, this is not enough for us and we offset 100kg of CO2 with each purchase of a piece of jewelry by donating to the Chooose initiative. Since this is significantly more than the 0.4kg of CO2 consumed, Maren Jewellery is climate positive.

In a sustainability report, organizations report on their achievements and initiatives in the area of sustainability, specifically in relation to the topics of economy, ecology and social issues, during the financial year and draw up a summary. Alongside the annual report, it is therefore an important information tool for companies to report annually on the sustainable development progress made by the organization and to inform interested parties about the sustainable orientation.

Read our sustainability report

Yes, although it is not mandatory for Maren Jewellery 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 therefore 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 get our synthetic diamonds, our recycled gold and silver, and who produces it for us. You'll get a detailed overview of our holistically sustainable supply chain and our values and goals. This way, you can see for yourself that our holistic understanding of sustainability is first and foremost, and that it is not just empty words.

Read our sustainability report

Yes, every year in July we create a new sustainability report for you and for ourselves in order to reassess our initiatives and activities and to become aware of successes, weaknesses and potential. Because in our opinion, growth in the sense of understanding is only possible if we deal openly with weaknesses. Only if we regularly make ourselves aware of where our weak points lie can we react adequately to them and improve. Not only for us, but above all for nature. And we want to make this possible with regular sustainability reporting. Because this is also mindfulness for us. Maren Jewellery is not a closed, finished company, but dynamic. We want to move, we want to grow and learn. We want to challenge ourselves. We have goals, like the circular economy, that we want to achieve.

RJC Certification (Jewelry Certification)

As a non-profit organization, the Responsible Jewellery Council (RJC) goal with its certification is to encourage jewelry companies to adopt responsible practices and supply chains from the mining of the precious metals and diamonds used to the distribution of the jewelry. In doing so, they place a special focus on the preservation of human rights, as well as ecological sustainability.

Fair Trade Gold Seal (Jewelry Certification)

The Fairtrade Gold label advocates for small-scale gold mining, their workers and families, and communities. By imposing strict and responsible regulations on occupational health and safety and pricing policies, and by charging Fairtrade premiums on products, it helps miners to improve their social and economic situation on their own. Child labor is strictly prohibited and adherence to strict mining criteria not only protects the workers in the long term, but also our environment.

Fairmined seal (jewelry certification)

The Fairmined seal certifies responsibly mined gold from small-scale mining organizations to achieve sustainable change in social and environmental conditions in artisanal small-scale mining and to promote sustainable development and environmental protection.

B Corporation

The international certificate‚Benefit Corporation‘ or 'B Corp' for short, certifies companies that are aware of their social, economic and ecological responsibilities and use them transparently to bring about sustainable and positive change in the global economy. For the certificate-awarding non-profit organization B Lab, this is given when profit maximization does not come first at any price, but the needs of all interest groups are bindingly taken into account and placed at the center of entrepreneurial action. Certified companies commit to behaving in accordance with the B Corp guidelines and are regularly re-measured against them.

Maren Jewellery is also a B Corp.

CO2 Neutral

Companies that are CO2 Neutral certified take responsibility for the CO2 emissions generated in the production and delivery of their products or services and fully offset them. In addition, they strive to reduce future greenhouse gas emissions.

Cradle to cradle

The Cradle to Cradle Certified® Product Standard is a globally recognized benchmark in the assessment of sustainable, safe, socially responsible and circular manufacturing of products. The certificate aims to ensure that all certified products have a positive impact on people and the environment and encourages companies to use sustainable, innovative and advanced materials and methods.

Yes, Maren Jewellery is a B Corp, which means that we have received a sustainability certificate for taking seriously the social and societal responsibility that comes with any startup. For focusing on the needs of those who are directly or indirectly affected by the activities of our business. These may be employees, suppliers or customers. All those who are interested in the long-term existence of Maren Jewellery. We also make sure to work with suppliers who also have sustainability certificates. Three of our partners are e.g. RJC certified.

In addition, we are currently working on two further sustainability certifications: the Responsible Jewellery Council (RJC) certificate, which was established specifically for jewelry, and the CO2 Neutral certification.

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 therefore sustainable because it is timeless, does not follow trends, can be combined with everything and is therefore particularly long wearable.

In addition, minimalist jewelry saves resources. Because everything that is superfluous is dispensed with. That's why when we create our simple designs at Maren Jewellery, we focus on exactly what 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. Not only does this result in a clean, uncluttered design language, it also ensures that we minimize our consumption of resources. That's why minimalist jewelry is sustainable, because it focuses on the essentials and cuts out everything else.

Recycled gold

Recycling gold avoids the mining and consumption of new, finite resources, because many production wastes or old recyclable goods already contain enough gold to be processed for reuse. Since gold can be melted down and reused over and over again without loss, recycling gold is an environmentally friendly and also people-friendly alternative. Gold mining is not only dangerous and harmful to the health of all miners, but is unfortunately also often carried out by children and pollutes our water, soil and air through the use of cyanide and mercury. WWF, as well as Verein Rettet den Regenwald considers recycled gold to be the most sustainable form of gold mining and processing. It uses 550 times less CO2 and 8.9 times less water than virgin gold. In addition, recycling gold prevents tons of toxic mine waste from entering our water, displacing peoples due to mining, and cutting down forests that are important for our biodiversity. Since 48.6% of gold demand is due to jewelry industry demand, choosing recycled gold can make a significant difference: Imagine if all jewelry manufacturers used recycled gold..

For the recycled gold that we at Maren Jewellery use for our jewelry pieces, we work closely with our partner, the Refinery C.Hafner which 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 further scrap. For this purpose, the scrap is first weighed and then melted down so that the precious metal is homogenized and can then be cast into ingots. Samples are then taken from these ingots and quarried with lead. The lead absorbs the precious metals in the crucible and then dissipates in the heat. What remains is the precious metal grain. This grain is then hammered and rolled. Only now does the actual separation process begin - the separation of the precious metals. The material to be separated dissolves in aqua regia. There, the various precious metals contained in the material separate from each other and can be recovered in pure form: Palladium, platinum and gold. At the end of the gold separation process, pure gold sponge is obtained. This is melted down and granulated, and the result is impressive: recycled fine gold with 99.99 percent purity.

No, at Maren Jewellery we only use recycled gold, so no new gold needs to be mined for our jewelry. The recycled gold we get from our RJC certified Refinery C.Hafner, which recovers 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 neighboring EU countries. Also our Jewellery Casting Kauselmann works exclusively with recycled gold and thus prevents new gold mining.

Urban mining describes the process of processing raw materials that have already been extracted from goods that are no longer needed, such as old smartphones or vehicles, and returning them to the material cycle. Urban agglomerations are regarded as huge raw material depots in this context, as huge amounts of electronic waste accumulate there every year, the raw material recovery of which can save the mining of new resources. This also applies to gold mining, because the gold built into old PCs, vehicles or smartphones can be extracted and recycled. Thus, urban mining prevents new gold mining and makes sustainable recycled gold possible.

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 gold alloying. The best known alloys are 8 carat (also 330 gold), 14 carat, (also 550 gold) or 18 carat (also 750 gold). The 18 carat gold has the highest gold content of 75%. In terms of color, a distinction is made between a yellow gold, rose gold, red gold and white gold alloy. The different colors result from the different mixing ratios of the metals.

When it comes to gold alloy, we at Maren Jewellery have chosen to use only recycled 18 karat yellow gold and 18 karat white gold to create high quality, long lasting jewelry for you. Both gold alloys we use are 75% pure recycled gold. The difference in colors comes from the different mixing ratios. Our recycled yellow gold is composed of 75% pure gold, 15% silver and 10% copper. The recycled white gold is 75% pure gold, 4% silver, 7% copper and 14% palladium (a platinum metal).

Both the 18 carat and 750 gold designations indicate the total proportion of pure gold within a gold alloy, i.e. the fusion of different metals. The carat specification for gold is a unit of measurement for the proportion by weight that the pure gold occupies in the total mixture of the alloy - also called fineness. The fineness is expressed in 1/24 parts. The largest possible weight proportion of pure gold within a gold alloy would therefore be 24/24 parts by weight, i.e. 24 carats. The fineness of gold can also be expressed in weight percent. 18 carats then correspond to the highest possible 24 carat fineness exactly 75% gold content of the total mass of the alloy. The designation 750 gold, as a reference to the 75% gold content, therefore describes the same purity of the alloy and can be used synonymously.

The 18 carat specification for gold is a unit of measurement for the proportion by weight that gold occupies in the total 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 percentage by weight of pure gold 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-karat gold only achieves a purity of 99.99%.

For the processing of jewelry, 24 carat gold is not suitable, however, because 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 suitable for processing jewelry.

In fair jewelry, that is, jewelry made with metal and gemstones from fair trade, attention is paid to fair working conditions with fair payment and strict environmental and humane regulations in the mining of gold, and stones. Fair trade jewelry therefore significantly minimizes the damage to the environment. In addition, prospectors in fair trade mines continue to fight against the abuses of the industry, which is extremely worthy of support. However, Fair Trade jewelry is still made from newly mined metals that pollute our environment.

Recycled jewelry circumvents this problem, because by using recycled metals, no further harm is done to people and nature, and resources are used that are already there in abundance. Especially in the case of jewelry made of gold, the recycling process is productive because gold does not lose any of its purity or texture when melted down, making it wonderfully suitable for a circular economy.

Fair Trade Gold is mined 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 conventional mining standards. The fact that miners in fair trade mines are taking concrete action against abuses in the industry with new standards and environmentally and human-friendly regulations is also extremely worthy of support. However, fair trade gold is also newly mined gold that causes avoidable damage to our environment and for which miners expose themselves to great health risks. That is why we at Maren Jewellery have decided to use only recycled gold for our jewelry instead of fair trade gold.

Recycled silver

Just as with recycled gold, recycled silver prevents the mining and consumption of new, finite resources. Silver is also already in many production wastes or goods that are no longer needed and can be recycled from them for reuse. Silver can also be melted down without loss, so recycling silver is a sustainable way to protect people and the environment and use what is already there. Since silver is usually mined together with gold, the advantages of recycling silver are obvious: no miners have to expose themselves to life-threatening and health-damaging risks and our environment is protected. The recycling process of silver consumes 7-14 times less CO2 than newly mined silver. In addition, recycling silver also prevents tons of toxic mine waste from entering our water, displacing peoples due to mining, and cutting down forests that are important for our biodiversity.

Also the 925 sterling silver, which we process for our jewelry, is made by our partner of the Refinery C Hafner with the help of a silver recycling process. Just as with gold, we constantly collect all of our silver residues that are created 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 further scrap to 925 sterling silver. For this purpose, the scrap is also melted down here until it is homogenized and can be cast into ingots. Samples are then taken from these ingots and quarried with lead. The lead absorbs the precious metals in the crucible and then dissipates in the heat, leaving behind the precious metal grain. This grain is then hammered and rolled and dissolved in aqua regia so that it can be separated from other precious metals and made into our jewelry as recycled 925 sterling silver.

Sterling silver is a fusion, also called an alloy, of 92.5% pure, genuine silver and 7.5% copper. It therefore carries a silver fineness 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 creating jewelry. Therefore, sterling silver is the highest quality silver alloy used in jewelry production.

Sterling silver, also called 925 silver, is composed of 92.5% pure silver and 7.5% copper. It thus has a fineness of 92.5%. Since alloys with a higher silver fineness lose stability, 925 sterling silver is the highest quality silver used in jewelry making.

Eco Synthetic Diamonds

Synthetic diamonds are diamonds grown in the laboratory. They are visually, in their hardness and in their chemical composition identical to natural diamonds. The advantage of synthetic diamonds, however, lies in their sustainable and humane extraction, because this neither pollutes our environment, nor are people in crisis areas endangered in the process. There are two techniques for the production of synthetic diamonds: the CVD process and the HTHP process.

In the Chemical Vapour Disposition (CVD) diamonds are created in a plasma that is as hot as a small sun on earth. Our partner Diamond Foundry manufactures novel plasma reactors for this purpose, which generate such heat that atoms attach to the natural diamond crystal lattice of a diamond used as a foundation in this process. So more and more atoms stack up on a thin foundation of diamond in this process, expanding the unique crystal structure of the seed diamond. Atom by atom, a pure, gem-sized synthetic rough diamond thus grows.

HTHP stands for High Temperature, High Pressure. In this process, which is modeled on the natural formation process of diamonds, graphite-2H is added to growth cells that are subjected to up to 70,000 bars of pressure from three sides in so-called cubic presses. Graphite-2H is a natural manifestation of the chemical element carbon, which has a hexagonal crystal structure similar to a honeycomb. The interior of the growth cell is first loaded with catalysts and seed diamonds and heated to approximately 1600-1700 degrees Celsius. Under these conditions, the graphite changes in a physicochemical process and the black powder grows into a transparent diamond. Our partner Swiss Diamond Vision works with the HPHT process to produce laboratory-grown synthetic Eco Diamonds.

The process of growing diamonds synthetically in the laboratory ensures that no people in crisis areas were endangered for the extraction of the diamonds. Because although lab-grown diamonds are just as pure and unique as natural diamonds, above all their origin is 100% secured: For example, the synthetic diamonds we use for Maren Jewellery come exclusively from Switzerland or America. This means that our gemstones are 100% of conflict-free origin. In addition, lab grown diamonds are resource efficient. If 1ct of diamond is mined in the conventional way, up to 200 tons of earth have to be moved for it. Moving these masses takes an incredible amount of energy. Our synthetic diamonds are much more environmentally friendly than natural diamonds. They consume 4.7-9.19 times less CO2 than normal diamonds. Although the high energy required for the growing process is also problematic, this is thought of at our partner the Diamond Foundry, which, just like Maren Jewellery, is a CO2 neutral company.

Our sustainability report

At Maren Jewellery, we source our Eco synthetic diamonds from two different, highly valued partners* who share our vision of sustainable, responsible stewardship of our earth.

Some of our jewelry is therefore made of synthetic diamonds from the Diamond Foundry, which grows Eco synthetic diamonds in the USA using the CVD process. The other part of our jewelry is made of synthetic diamonds of the Swiss Diamond Vision. These were grown with the help of HTHP technology in the laboratory in Switzerland.

It is very important to us that you are always informed about the origin of all individual parts when buying one of our pieces of jewelry. Therefore, on our product pages you will of course find out quite transparently for each piece of jewelry whether the diamonds processed in it come from the Diamond Foundry or Swiss Diamond Vision.

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

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

Color: Indicates the hue of the diamond in gradations from D=colorless to Z=colorfull hue.

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

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

Synthetic diamonds grown in the laboratory are also classified using the 4 C's.

At Maren Jewellery all diamonds have the color G=almost colorless, a clarity of VS1, so only very small inclusions and the cut quality 'excellent'. From a carat weight of more than 0.5, all our diamonds are delivered with an official diamond certificate.

Engagement rings

A sustainable engagement ring is a symbolic ring that has been produced from sustainable fair trade or recycled metals under mindful and responsible standards and is of high quality, long lasting. If it is set with gemstones, they should be fair trade, certified and traceable, or grown directly in a lab. Furthermore, it should have been produced under fair and humane conditions. Since jewelry is always handmade, if the price is low, it can be assumed that either children were employed or workers* were not paid well. Therefore, it is very important to get accurate information about the production. Sustainable companies will answer every question openly and transparently.

An engagement is a very emotional and personal moment of love that the engagement ring symbolically captures for eternity. Therefore, when choosing an engagement ring, many people find it important that it does justice to the preciousness of the moment and the love and look for a ring with precious stones. It is essential to make sure that the gemstones of the engagement ring are fair trade, 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 graded using the 4 C's to determine the quality of the stones and therefore the entire piece of jewelry.

The easiest way to find out the ring size for an engagement ring is to already have a ring from your partner as a yardstick, which fits him or her well on the corresponding finger. On every product page of Maren Jewellery you will find next to the size selection field our Size Guide to download or print, on which you can easily 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 matching ring at hand, you can find out the ring size by cutting out our measuring tape from the Size Guide and cutting in at the dotted line. Now all you have to do is put the tape measure around your partner's finger and read off the ideal ring size.

In general, it is safe to order engagement rings or other high-quality goods online if you do so from trustworthy sellers. Therefore, when buying online, always make sure that you can trace the origin of the jewelry and, if applicable, the diamond in your ring. Reputable retailers are happy to hear 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 for your online purchase. A special advantage of buying your engagement ring online is the fact that you can get an overview of the information and details that are important to you in peace and quiet, independent of store opening hours. And should you still not be satisfied with your choice, you can always make use of your 2-week return policy.

Wedding rings

Wedding rings stand as a sign of shared love, why shouldn't they also stand as a symbol of love for our earth at the same time? 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 also make us think with a clear conscience about the beauty of our earth where our love takes place.

We at Maren Jewellery find this the most beautiful and original form of love on the finger. We have therefore created wedding rings such as the Bold Essential Ring or Essential Ring designed from recycled yellow gold or white gold, which are not only beautiful, elegant wedding rings, but also just sustainably produced in harmony with our nature.

Wedding rings are the most symbolic and emotionally important piece of jewelry in the lives of many couples. Wedding rings should not only last a lifetime, but also please for a lifetime. In addition, it is important to many couples that the symbols of love worn on their fingers have also been produced in harmony with people and nature and can be worn with a clear conscience. Then the choice falls on sustainable wedding rings. To ensure sustainability when buying wedding rings, some criteria should be taken into account when choosing. The rings should be made of high-quality, sustainable materials, such as recycled metals or fair trade metals, and should 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 fashion. Another important factor is production. Sustainable wedding rings should be produced as locally as possible under fair working conditions and with fair wages. Since jewelry is always handmade, if the price is low, it can be assumed that either children were employed or workers *were not well paid. Therefore, it is very important to get accurate information about the production. Sustainable companies will answer any question openly and transparently.

Yes, at Maren Jewellery all jewelry made from gold is recycled gold, including our wedding rings.

A circular economy is a process model in which the life cycle of materials and products is extended and prolonged as long as possible so that new resources are conserved. This is done by using goods as long and frequently as possible and maintaining their functionality. If this no longer succeeds, they are recycled at the end of their life cycle and reused to create new goods. This idea allows materials once mined and manufactured to flow into a cycle of reuse and avoid the extraction of new resources as much as possible.

More Infos

Until now, there are hardly any jewelry companies that rely on a circular economy in jewelry production. We at Maren Jewellery would like to change that, because especially the metals used in jewelry can be melted down again and again with high purity and without loss. That is why we at Maren Jewellery use only high quality, reusable materials such as recycled metals that can be easily repaired and also melted down again and again.

Since we focus on this already during the design, all our jewelry pieces areDesigned for Deconstruction. This means that they can be dismantled back into their individual parts, melted down and recycled at any time. In the long term, it is therefore our goal to offer a take-back of all jewelry pieces in order to produce new jewelry pieces from the materials according to the wishes of our customers. This would enable us internally from our own pieces to let our used resources themselves flow into a waste-free cycle, to ensure circularity and to avoid unnecessary waste production. In order to preserve the jewelry as long as possible, we offer repairs and refurbishments at any time.

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. But the bottom line is this: If you love your jewelry, you should show it with proper jewelry care. Polish it, give it a soap bath and a proper jewelry box. Then you can not only enjoy your jewelry for a long time, but it will also stay with you longer. This is also an aspect of sustainability. Because if we take care of what we already own and look after it in the best possible way, we will have to consume less new things and do our earth a favor.

The care of 18 carat gold jewelry, as we produce it exclusively at Maren Jewellery, is very easy due to its purity and therefore very resistant material. Gold jewelry is super easy to clean and maintain and is therefore especially durable. When your gold jewelry fades, 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 well cared for and shine new again, just like before.

The care of silver jewelry is quite simple, if you consider a few tips. Perhaps first something basic: Why does silver jewelry tarnish in the first place? Silver oxidizes. This is the term used to describe the reaction of silver jewelry with oxygen. Oxidation causes the jewelry to tarnish darkly and look dirty. This is a completely natural process that is not bad at first. But because oxygen tarnishes your silver jewelry, it's best to store it as airtight as possible. Jewelry boxes or similar are suitable for this purpose. And if your silver jewelry does tarnish, you can easily clean out the tarnished areas with a silver cleaning cloth and restore your jewelry to its former glory.

More Infos

Sterling silver, or 925 silver, is solid silver that is water resistant due to its high fineness and does not discolor upon contact with water. However, sterling silver can react with oxygen and oxidize. Oxidation causes the jewelry to tarnish darkly and appear dirty. This is a completely natural process that is not a bad thing. This is because tarnishing can be minimized by storing in airtight containers. If it does happen, you can easily clean out the tarnished areas with a silver polishing cloth or a silver bath.

Diamond jewelry and therefore also our synthetic Eco diamonds need the right care to keep their shine permanently. Because even though diamond is one of the hardest materials, it can suffer great damage without the right care. For example, when diamond jewelry is exposed to large temperature fluctuations or when it comes into contact with perfume, cosmetics or household chemicals. But this won'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 little soap and a soft cloth. If you regularly treat your favorite piece with care, it will last a lifetime.

At Maren Jewellery it is important to us that our holistic mindful and sustainable vision also includes the packaging of our jewelry. Our jewelry is therefore shipped in recycled paper artwork, where the printing as well as the embossing and even the glue is environmentally friendly and completely plastic-free. Depending on your preference, you will receive our jewelry either in recyclable paper boxes or in a beautiful, sustainable linen bag. If you wish, we can also gift wrap our jewelry for you. Around our embossed wrapping paper we put a hand-woven ribbon, which can be worn as a wish bracelet after opening - before putting it on, a wish is made and when the bracelet falls off, the wish comes true.
