Gold jewelry: Expert on the use of recycled gold
More jewelry ideas
We at Maren Jewellery use recycled gold for our gold jewelry because existing gold is reused for our pieces instead of using newly mined gold. We want to make the choice of materials for our pieces understandable and transparent at all times. Learn more about the life cycle assessment of our pieces and our approach to the materials used.
Not all gold is the same: Depending on the alloy, gold jewelry differs, among other things, in its fine gold content and its properties. For our gold jewelry, we use recycled 14 and 18 karat gold. 14 karat gold, also known as 585 gold, contains 58.5% pure gold. In 18 karat, or 750 gold, the pure gold content is 75%. Pure fine gold is comparatively soft and is therefore alloyed with other metals for jewelry. Depending on the composition, this creates different properties and shades. At Maren Jewellery, you’ll find jewelry made of yellow gold and white gold. If you still don’t know which gold color suits you best, you can find more in our journal about the effect of different 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.
Jewellery made of gold 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. In this way, we use already existing gold again for our jewellery pieces and keep it in a material cycle. We document origin and processing along our supply chain. In addition, we support the Earthbeat Foundation, a nonprofit organisation that addresses conditions and impacts in the gold sector. Every purchase of a gold piece of jewellery at Maren Jewellery supports this project.
Frequent questions about our gold jewelry
What does the "750" stamp on gold jewelry mean?
The 750 hallmark on your gold piece shows you the alloy — in other words, 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 stated in thousandths by weight. The lower the number, the less gold is contained in the alloy (that is, the precious-metal mix) used for the piece of jewelry. In 750 gold, the jewelry therefore consists of 75 % fine gold.
How do I store gold jewelry?
So that your gold jewelry doesn’t lose its shine and stays 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 keep real gold rings, earrings, bracelets, and chains separately to protect them from scratches. For rings, a slightly more compact ring box is also a good option. It’s best if you also gently clean your gold jewelry before storing it, as described in the next question. If you’re often on the go or traveling, our travel jewelry case is a great and compact solution for storing your jewelry safely and neatly. For the bedside table or dresser, we also have beautiful ceramic bowls and -plates, which offer a practical and stylish place to keep them in everyday life.
How do I clean gold jewelry?
Even though real gold jewelry is very durable and hardly tarnishes in high-quality alloys, valuable pieces of jewelry still need regular care to maintain their brilliant shine over time. Especially if you wear your jewelry every day, the surface is affected by things like skin oils, cosmetics, sweat, or soap residue. To preserve or restore the shine, you should therefore clean your jewelry regularly. You can either use professional cleaning services or try different cleaning methods yourself. Whether cleaning with dish soap, baking soda, aluminum foil, vinegar, or using special cleaning kits makes sense depends on the piece of jewelry and the type of dirt. In our journal ‘Cleaning gold jewelry: this makes it easy’ we cover the individual cases and explain suitable methods and the specific procedure.
What is the difference between 14K, 18K, and 24K gold?
For information about gold content in karats, this is an older but still very common marking in the jewelry industry, where the weight share (also fineness) of gold is given in 1/24 parts. 8 karats then correspond to 333 gold, 14 karats to 585 gold, and 18 karats correspond to 750 gold.
How do I verify the authenticity of gold jewelry?
An important indication of the fineness of gold jewelry is the fineness hallmark. Details such as 585 (14 karats) or 750 (18 karats) show the gold content of the alloy. However, a missing hallmark does not automatically mean that it is only gold-plated metal. If you are unsure about the authenticity or alloy of a piece of jewelry, a professional inspection can provide clarity.
