Gold jewelry: Expert on the use of recycled gold

Can you still wear gold jewelry with a clear conscience today? At Maren Jewellery, we use recycled gold because existing gold is reused for our jewelry pieces instead of newly mined gold. We believe it makes the jewelry even more beautiful when you keep that in mind, and we want our jewelry materials to be understandable and transparent at all times. Learn more about the environmental footprint of our jewelry pieces and our approach to the materials we use.
Gold is not the same as gold, and sometimes it is not easy at first glance to recognize the differences between gold alloys and understand how they are priced. Whether white gold or yellow gold, all our pieces contain a high proportion of pure gold — also known as fine gold. However, pure fine gold is unsuitable for making jewelry because it is very soft and prone to damage. That is why other precious metals are added to make the gold jewelry more durable. All our pieces are made of 75 % recycled fine gold, and this high proportion gives them their warm yellow-gold or bright, light-reflecting white-gold color. The difference in color comes from the different mixing ratios. The gold content of our jewelry remains the same: recycled 750 gold or 18 karat, the highest-quality gold alloy suitable for making jewelry. If you still do not know whether you are more of a yellow gold or white gold type, you can gather information in our journal about the effects of jewelry colors.
Are you still unsure about feeling comfortable buying gold jewelry online because you would like to see and try it on beforehand and worry that it might not arrive safely? We can ease your concerns because we believe there is nothing more convenient than trying the jewelry at home in peace with different outfits. For wedding rings, you can even put together a trial set, and for the right ring size, we have a ring sizer ready. If you have questions or individual ideas, our ring designer Helge is always available for a consultation. If you are still not convinced, you can return your gold jewelry to us within 2 weeks. Of course, we also insure the shipping, so nothing can go wrong with your order.

Recycling gold jewelry designed by jewelry designer Helge Maren
For Helge Maren Hauptmann, jewelry is something deeply personal. It preserves memories, tells stories, and often stays with us for a lifetime. This mindset shapes every piece of jewelry from Maren Jewellery.
After studying jewelry design in Pforzheim and spending many years in the industry, the designer founded Maren Jewellery in 2020 to create jewelry according to her own values: handcrafted and defined by a quiet luxury aesthetic. Using recycled gold and lab-grown diamonds, she creates pieces that do not need to be loud to make an impact—for women who value timeless design and a traceable origin of materials.
Gold jewellery stands for quality, durability, and luxury. It can be passed down through generations and preserve memories. For our gold jewellery, we use only recycled gold obtained through urban mining. This keeps existing gold in the material cycle and helps reduce the demand for newly mined gold. With recycled gold, we are therefore taking a big step toward the circular economy. We document origin and processing throughout our supply chain and also support the Earthbeat Foundation, a non-profit organization focused on safer and more environmentally friendly practices in the gold sector as well as the impacts of gold mining. Every purchase of a gold piece of jewellery from Maren Jewellery helps support this project.
Frequent questions about our gold jewelry
What does the "750" stamp on gold jewelry mean?
The 750 stamp on your gold jewelry indicates the alloy – that is, the proportion of pure fine gold used in your gold jewelry. In Germany, 333 gold, 585 gold, and 750 gold are common. The gold content is given in thousandths by weight. The smaller the number, the less gold is actually contained in the alloy (the precious metal mixture) used for the piece of jewelry. With 750 gold, the piece consists of 75% fine gold.
How do I store gold jewelry?
To keep your gold jewelry from losing its shine and to keep it beautiful for a long time, you should store it airtight and dry, away from sunlight. A jewelry box is ideal for this, where you can store real gold rings, earrings, bracelets, and necklaces separately to protect them from scratches. For rings, a more compact ring box is also a good option. It's best if you gently clean your gold jewelry before storing it, as described in the next question. If you travel a lot or are often on the go, our travel jewelry case is a great and compact solution to store your jewelry safely and securely. For your nightstand or dresser, we also have beautiful ceramic bowls and dishes that offer a practical and stylish storage option for everyday use.
How do I clean gold jewelry?
Even though real gold jewelry is very durable and high-quality alloys hardly tarnish, valuable pieces of jewelry still require regular care to maintain their brilliant shine over time. Especially if you wear your jewelry daily, the shiny surface can quickly be affected by things like skin oils, cosmetics, sweat, wastewater, or soap residue. To prevent scratches and maintain or restore the original shine, you should therefore clean your jewelry regularly . You can use professional cleaning services or try various cleaning methods yourself. Whether cleaning with dish soap, baking powder or baking soda, aluminum foil, vinegar, or using special cleaning kits is suitable depends on the piece of jewelry and the type of dirt. In our journal 'Cleaning Gold Jewelry: How to Do It Easily,' we cover individual cases and explain suitable methods and specific procedures. After cleaning, you should always finish with a polish to restore the shine.
What is the difference between 14K, 18K, and 24K gold?
When it comes to gold content in carats, this is an older but still very common designation in the jewelry industry, where the weight proportion (also called fineness) of gold is given in 1/24 parts. 8 carats correspond to 333 gold, 14 carats to 585 gold, and 18 carats to 750 gold.
How do I verify the authenticity of gold jewelry?
The most reliable indication of the quality and authenticity of gold jewelry is the fineness stamp. In real gold jewelry, you will always find the gold content as an engraved number. The number 585 (14 carat) or 750 (18 carat) thus tells you about the alloy, while real silver is stamped with 925. If such a stamp is missing, it probably indicates that it is only silver-plated or gold-plated metal.
