FAQ

Sustainable jewelry refers to pieces in which ecological and social criteria are taken into account in the selection of materials, manufacturing, use, and packaging.

This can include, for example, recycled or certified fair-trade metals, traceable or lab-grown gemstones, durable materials, timeless design, and packaging that conserves resources as much as possible. Fair working conditions, safe production standards, and transparent information about the supply chain are also important criteria.

Sustainability does not result from a single feature, but from the transparent combination of several verifiable measures. You can find more information about our criteria, materials, and supply chains in our Sustainability Report.

We consider ecological and social criteria throughout the entire lifecycle of our jewelry pieces – from material selection and design and production through to packaging and later refinishing.

We use exclusively recycled gold and silver as well as lab-grown diamonds. Our jewelry pieces are made in Germany according to the made-to-order principle and are designed for longevity, repair, redesign, and recycling. In addition, we offer repairs, professional refinishing, and the redesign of existing jewelry pieces.

Maren Jewellery is B Corp™ and Responsible Jewellery Council (RJC) certified. We are also committed to transparent supply chains and a circular economy – among other things through our participation in Circular Monday and Fashion Revolution Week.

You can find more information about our materials, supply chains, certifications, and our approach to sustainability in our Sustainability Report, our Supply Chain Policy, and the Due Diligence Report.

Maren Jewellery supports selected social and environmental initiatives that align with our sustainability approach.

Earthbeat Foundation: We donate 3% of our annual profit to the Earthbeat Foundation. The organization supports people whose livelihoods depend on small-scale mining in building alternative sources of income, for example through beekeeping or sustainable agriculture.

Chooose: For our calculated residual emissions, we support certified climate protection projects through Chooose. For every piece of jewelry sold, we make a contribution to funding these projects. We publish information on our emissions calculation, the amount of the contribution, and the supported projects transparently in our sustainability report.

Further information about our giving-back approach and the supported projects can be found in our sustainability report

A sustainability report describes which measures, key figures, and developments a company documents in the areas of ecology, social responsibility, and corporate governance over a specific period of time.

For example, it may contain information on materials, supply chains, emissions, social standards, goals, and progress. This helps customers and other interested parties better understand sustainability claims.

Yes. Since 2021, Maren Jewellery has published a sustainability report every year – even though, as a small company, we are not currently legally required to do so.

With our sustainability report, we aim to provide transparent information about our environmental and social responsibility. Among other things, we therefore publish information about our materials, supply chains, certifications, CO₂ emissions, climate protection measures, as well as our goals and progress.

For us, sustainability is not a state, but a continuous process. The sustainability report helps us regularly review our measures, make progress measurable, and identify areas for improvement. This allows us to continuously incorporate new insights, innovative materials, and more sustainable solutions into our work and further develop our sustainability approach year after year.

At the same time, we want to give our customers the opportunity to transparently follow our development and form their own impression of our measures and their impact.

Go to the sustainability report

Yes. We publish our sustainability report annually and review our metrics, measures, and goals in the process.

Since sustainability is an ongoing process and there are always new insights, materials, and opportunities, we use the report to transparently document our progress and continuously further develop our sustainability approach.

At Maren Jewellery, we focus on minimalist jewelry design because timeless pieces are often worn for many years and are less dependent on short-lived trends. Our goal is to create jewelry that stays with people for a lifetime and brings joy across generations.

We combine this design philosophy with high-quality, durable materials such as recycled gold and silver, as well as lab-grown diamonds. This is complemented by repair, refurbishment, and remodeling services so that jewelry pieces can be used for as long as possible.

You can find out more about our design philosophy in our journal article  “Minimalism – more than a trend”

Recycled gold comes from existing gold stocks, for example from scrap gold, jewelry, industrial, or production leftovers. This can reduce the need for newly mined gold. Since gold can be melted down and reprocessed again and again without any loss of quality, it is particularly well suited to a circular economy.

That is why Maren Jewellery uses only recycled gold for its jewelry pieces. Compared to newly mined gold, recycled gold may have lower environmental impacts—depending on manufacturing processes, energy sources, and underlying data—for example in terms of CO₂ emissions or resource consumption.

You can learn more about our recycled gold, the underlying data, and the comparison with newly mined gold in our journal Recycled Gold and in our Sustainability Report . You can also find information on the environmental impacts of gold mining from the WWF and from Save the Rainforest

Recycled gold uses already extracted gold stocks, for example from scrap gold, industrial, or production leftovers. This can reduce the need for newly mined gold.

Gold can be melted down again without any loss of quality and processed into new alloys. Compared to newly mined gold, recycling can have ecological advantages—depending on the method, energy source, and underlying data—for example in terms of CO2e emissions, water consumption, and avoided mining impacts.

We document specific comparative values and sources for the materials used by Maren Jewellery in or on the linked material pages.

More info

We work with the precious metal refinery C.Hafner in Germany for our recycled gold. There, gold scraps and other precious metal-containing materials are collected, melted down, and separated into their individual precious metals. The gold is then refined into fine gold with a purity of 99.99% and can be further processed into new pieces of jewelry.

Because gold can be recycled again and again without any loss of quality, the raw material remains permanently in circulation. This means that existing gold stocks can be reused time and again to create new pieces of jewelry.

You can find out more about our partner C.Hafner and the recycling process in our Meet the Maker Journal Precious Metal Refinery C.Hafner.

We use exclusively recycled gold for the vast majority of our gold jewelry pieces. We source it from the RJC-certified refinery C.Hafner, which recovers gold from sources including old gold, jewelry, electronics, and dental technology, and processes it into new fine gold. According to our partner, the source materials come predominantly from Germany and neighboring EU countries.

Our Fairmined gold chain is an exception. For this jewelry piece, we use certified Fairmined Gold, which comes from responsibly operated artisanal and small-scale mining and is sourced according to Fairmined standards.

You can learn more about our recycled gold in our journals The C.Hafner Refinery & in the Urban Mining Journal.

Urban Mining refers to the recovery of valuable raw materials from existing products, such as old jewelry, electronics, or production leftovers. Instead of extracting new raw materials, existing materials are recycled and returned to the material cycle.

The recycled gold used by Maren Jewellery is also based on this principle. This allows valuable precious metals to be used again and again without any loss of quality, reducing the need for newly mined gold.

You can find out more about urban mining and our materials in our journal: Urban Mining

Pure gold is very soft for jewelry making. That is why it is alloyed with other metals such as silver, copper, or palladium. This mixture is referred to as a  gold alloy  and gives the jewelry its hardness, color, and suitability for everyday wear.

The best-known alloys are  8 carat (333),  14 carat (585) , and  18 carat (750)  gold. Depending on the composition, different gold colors are created, such as yellow gold, rose gold, or white gold.

You can learn more about gold alloys and their properties in our journal  Gold alloys.

Maren Jewellery uses—depending on the piece— 8-carat (333), 14-carat (585) and 18-carat (750) gold in yellow gold, white gold, and rose gold. Which alloy is used depends on the respective design as well as the requirements for durability, comfort, and appearance.

You can learn more about the differences between the gold alloys and their properties in our journal Gold Alloys in Jewelry. You can also find information about the origin of our gold on our materials page about recycled gold.

Recycled Gold comes from existing gold stocks, such as scrap gold, jewelry, or production remnants. It is reprocessed and can be used again and again for new pieces of jewelry without any loss of quality. This helps reduce the need for newly mined gold.

Fairmined Gold , on the other hand, comes from certified artisanal and small-scale mining. The Fairmined standard promotes responsible working conditions, fair pay, and environmental and social standards in the participating mining communities.

For the majority of our range, Maren Jewellery uses recycled gold. With our Fairmined Gold Necklace , we also offer a piece of jewelry made from certified Fairmined Gold.

You can learn more about our recycled gold on our materials page as well as in our journal article on Urban Mining Information about our Fairmined Gold Necklace can be found on the product page.

Recycled silver comes from existing silver stocks, for example from reclaimed materials or production leftovers. This can reduce the need for newly mined silver. Since silver can be melted down again, refined, and processed into new alloys, it is well suited to a circular economy.

That is why Maren Jewellery uses only recycled silver for its jewelry pieces. Compared with newly mined silver, recycled silver can have lower environmental impacts, depending on manufacturing processes, energy sources, and underlying data.

You can find out more about our recycled silver and its origin on our  materials page

Yes. Sterling silver is real silver. It consists of 92.5% fine silver and 7.5% other metals, usually copper. That is why it is also called 925 silver .

Pure silver would be too soft for jewelry making. The alloy makes the material significantly more durable and better suited for long-lasting jewelry 

925 sterling silver is one of the most commonly used silver alloys for high-quality jewelry. It consists of 92.5% fine silver and 7.5% other metals, usually copper.

This alloy makes sterling silver significantly more durable than pure silver, which is why it is particularly well suited for long-lasting jewelry. For this reason, Maren Jewellery uses only recycled 925 sterling silver for its silver jewelry pieces.

Lab-grown diamonds are created under controlled conditions in a laboratory. They have the same chemical composition, hardness, and the same optical and physical properties as natural diamonds. The difference lies in how they are formed: while natural diamonds develop in the earth over millions of years, lab-grown diamonds are produced within just a few weeks using modern technologies.

At Maren Jewellery, we use lab-grown diamonds from our partner Fenix Diamonds, which are produced using the CVD process (Chemical Vapour Deposition) . They are traceable all the way back to their origin. Because no traditional diamond mining is required for their production, the impact on landscapes and ecosystems can be reduced compared to conventional diamond mining.

You can learn more about our lab-grown diamonds and how they are made in our journal: "How are diamonds grown in a laboratory?"

Compared to naturally mined diamonds, lab-grown diamonds can enable a more responsible use of resources, as no conventional diamond mining is required for their production. This can reduce interventions in landscapes and ecosystems. At the same time, their production requires energy.

That is why, when selecting our partners, we pay attention to transparency, traceability, and responsible production standards. We source our lab-grown diamonds from  Fenix Diamonds in India. The diamonds are traceable back to their origin. Fenix Diamonds states that it produces in a climate-neutral way and uses solar energy, among other things.

The quality of diamonds is assessed using the so-called  4 Cs :

• Carat: Describes the weight of the diamond. One carat equals  0,2 grams.
• Color: Assesses the color of the diamond on a scale from  D (colorless) to  Z (noticeably tinted).
• Clarity: Describes natural characteristics and inclusions in the diamond.
• Cut: Assesses the quality of the cut and, among other things, the diamond’s brilliance.

These quality characteristics apply to both  natural  and  lab-grown diamonds.

At Maren Jewellery, we use lab-grown diamonds with color grades  D–G (colorless to near-colorless), a clarity of  VVS to VS , and a cut quality of  Very Good  to  Excellent. Starting from a diamond weight of  0,5 carat , we supply our diamonds with an official diamond certificate.

An engagement ring can be made more responsibly when its materials, origin, and production are transparently traceable. This includes, for example, recycled or certified Fairmined gold, lab-grown or transparently traceable diamonds, durable craftsmanship, and options for repair and refinishing.

At Maren Jewellery, our engagement rings are handcrafted in Germany . We use recycled gold and lab-grown diamonds, focus on durable design, and offer repair, refinishing, and remodelling services. We publish transparent information about our materials, supply chains, and certifications in our sustainability report.

You can find out more on our website on the following pages: our engagement rings our materials and our sustainability report.

When buying a diamond engagement ring, it is worth paying attention not only to the design but also to the quality, origin, and transparency . Important quality criteria are the so-called 4 Cs: Carat, Color, Clarity and Cut.

Equally important is transparent information about the origin of the diamond and how it was created. At Maren Jewellery, we use only lab-grown diamonds that can be traced back to their origin. For diamonds weighing 0.5 carat or more, we provide our diamonds with an official diamond certificate.

You can learn more about the 4 Cs in our journal The 4 Cs – How Diamond Quality Is Evaluated You can also find information about our lab-grown diamonds in our journal How Are Diamonds Grown in the Laboratory?.

There are various ways to determine the right ring size. The easiest is to use a ring that fits well on the desired finger. With our  Size Guide, you can conveniently measure it at home.

If you don’t have a suitable ring, you can alternatively use our ring sizer or a strip of paper to measure the circumference of your finger. Since ring size can vary slightly depending on the time of day, temperature, or hand, we recommend measuring on several days.

If, despite all care, you happen to choose the wrong size, that’s no problem: We will adjust your ring to the correct size free of charge as part of our service – even for engraved engagement and wedding rings.

You can find more tips on measuring ring size in our journal How can I determine my ring size?

Yes – if you buy from a trustworthy provider. Make sure that information about materials, origin, certifications, and production is provided transparently. Reputable providers answer questions openly, offer personal advice, and provide clear information about their jewelry pieces.

At Maren Jewellery, we personally guide you through selecting your engagement ring. We provide transparent information about our materials, supply chains, and production, and are always there to help with any questions. We also offer individual consultations as well as a ring sizing service.

When buying wedding rings, it is worth paying attention to transparent material sourcing, high-quality craftsmanship, and clear information about how they are made. Criteria such as durability, repair options, and the materials used can also play an important role.

At Maren Jewellery, our wedding rings are handcrafted in Germany and made from recycled gold. We transparently publish information about our materials, supply chains, certifications, and sustainability approach in our sustainability report. In addition, we are B Corp™ and Responsible Jewellery Council (RJC) certified.

You can find out more about our wedding rings and our sustainability approach on our Wedding Rings page as well as in our sustainability report.

Yes. Our wedding rings are made from recycled gold . Gold can be recycled again and again without any loss of quality and crafted into new pieces of jewelry. This allows existing gold reserves to continue being used and reduces the need for newly mined gold.

You can find out more about our recycled gold and its origin on our materials page as well as in our journal Urban Mining

At Maren Jewellery, all pieces of jewelry are created  in Germany and are only made after an order is placed, following the  made-to-order principle . This means we only produce what is actually ordered and can avoid overproduction.

Each piece of jewelry is designed by founder Helge Maren and crafted together with selected manufacturers and family-run businesses that have been long-standing partners of Maren Jewellery. From casting and setting the lab-grown diamonds to engraving, we work with specialized artisan workshops. Finishing, polishing, quality control, and packaging take place at the Maren Studio on Lake Chiemsee.

For our jewelry, we primarily use recycled gold and silver as well as lab-grown diamonds. Our designs are made to last and can be repaired, refinished, and, if needed, redesigned. In this way, we aim to keep materials in circulation for as long as possible.

We expect our partners to comply with our  Supply Chain Policy and defined social and supply chain-related standards. We explicitly reject child labor and forced labor. Maren Jewellery is also  B Corp™ and  Responsible Jewellery Council (RJC) certified and publishes an annual Sustainability Report as well as a Due Diligence Report, to provide transparent information about materials, supply chains, goals, and progress.

You can find out more about our production and the people behind our jewelry on our page: Our Production or in our journal:  Fashion Revolution Week – Who made your jewellery?

Yes. Our jewelry pieces are carefully handcrafted in Germany. We source only individual earring backs and earring clasps from a selected partner in Europe who meets our standards for quality and materials. Our jewelry pieces are manufactured in Germany.

You can learn more about our production and the people behind our jewelry on our page Our Production

Made-to-Order means that we only craft your piece of jewelry after you place your order. This way, we produce only what is actually ordered and can avoid overproduction and unnecessary inventory.

Each piece of jewelry is handcrafted with care in Germany and shipped only after quality control is complete. This production principle allows us to use resources more consciously while ensuring the highest quality standards.

You can learn more about our production and our Made-to-Order principle on our page: Our Production.

Yes. Every piece of jewellery from Maren Jewellery is designed by us and then handcrafted in Germany with great care. From production and gemstone setting to quality control and packaging, we oversee every step with the utmost attention.

Our jewellery is made according to the made-to-order principle . This means that production usually only begins after you place your order. This allows us to avoid overproduction and create each piece individually.

You can find out more about our production and the people behind our jewellery on our page "Our Production" as well as in our journals Who made your jewellery? & working together.

The circular economy aims to keep valuable materials in circulation for as long as possible. Instead of disposing of raw materials after use, products are designed so they can be used for as long as possible, repaired, refurbished, reused, and recycled at the end of their life cycle.

Precious metals such as gold and silver are particularly well suited to this, as they can be reprocessed again and again and used for new pieces of jewelry. This helps conserve natural resources and reduce the need for newly extracted raw materials.

At Maren Jewellery, the circular economy begins with the design of our jewelry. We rely on recycled precious metals, durable design, and repair, refurbishment, and redesign services so that valuable materials remain in circulation for as long as possible.

Find out more about our circular economy approach in our journal: Circular Economy

In jewelry production, circular economy means keeping valuable materials in circulation for as long as possible. This is achieved through the use of recycled precious metals, durable design, repairs, refurbishment, and the reuse of jewelry and materials. In this way, natural resources are conserved and valuable raw materials are kept within the cycle.

We create our jewelry pieces exclusively from recycled gold and silver and already take into account in the design stage that they can be repaired, refurbished, and, if necessary, separated into their individual components. We describe this principle as Designed for Deconstruction. In addition, we offer repairs and the redesign of existing jewelry pieces so that precious metals can be used for as long as possible.

Our commitment goes beyond our products: through our participation in Circular Monday, we advocate for the promotion of the circular economy. During Fashion Revolution Week we create transparency about our supply chain and show the people behind our jewelry pieces.

Proper jewelry care helps ensure that your pieces stay beautiful for a long time and accompany you for many years. Regular cleaning, careful storage, and mindful handling of jewelry can extend its lifespan.

Different care measures are recommended depending on the material. Gold, sterling silver, and lab-grown diamonds each have different properties and should be cared for accordingly. If your jewelry ever needs a professional cleaning or refinishing, we’ll be happy to help.

You can find more tips on proper jewelry care in our journal: How do I care for my jewelry?

18-carat gold jewelry is generally easy to clean and care for. If needed, place your piece of jewelry in a lukewarm bath of water with mild soap and clean it carefully with a soft brush. You can then dry it with a soft cloth.

Please avoid harsh cleaning products, and for jewelry with stones or special finishes, check the appropriate care instructions.

You can find more information on cleaning gold jewelry in our Journal.

Silver jewelry can react with oxygen and tarnish as a result. This is a natural process and not a quality defect.

Store silver jewelry as dry as possible and protected from air. You can carefully clean tarnished areas with a suitable silver polishing cloth.

You can find more tips on cleaning your silver jewelry in our Journal.

Our jewelry pieces made of  925 sterling silver as well as  14- and 18-carat gold can generally come into contact with water. Gold usually does not discolor from water. Sterling silver can oxidize over time through contact with oxygen and other environmental influences, causing it to tarnish. This is a natural process and not a quality defect.

To keep your jewelry beautiful for a long time, we recommend removing it before swimming in chlorinated or salt water, as well as before contact with cosmetics, sunscreen, or cleaning products. If silver jewelry does tarnish, the surface can usually be cleaned again with a silver polishing cloth or a silver dip.

You can find more tips on caring for your jewelry in our journal  Summer jewelry – How to keep your jewelry beautiful for a long time

Diamond jewelry should be cared for regularly and gently so that its shine is preserved for as long as possible. Avoid extreme temperature fluctuations as well as contact with perfume, cosmetics, or household chemicals.

For cleaning, lukewarm water, a little mild soap, and a soft cloth are usually sufficient. If you are unsure or if there is heavier soiling, we recommend professional cleaning.

Here we offer our professional jewelry cleaning service.
