Recognize sustainable jewelry:
We are a certified RJC member
The Responsible Jewelery Council (RJC) is the leading international body for ethically, socially and ecologically responsible jewelery production. fejn jewelry is a member of the Council and is therefore committed to the values of the organization. For a fair tomorrow, the RJC relies on holistically sustainable value chains. This means that from material selection to the manufacturing process to supply chains and packaging choice, the question is always asked: “What is best for people and the environment?” Through our certification, we have made it clear to everyone what values fejn drives. Transparent and honest.
Let customers speak for us

What distinguishes sustainable jewelry?
For more and more brands, sustainability is a buzzword; for us, it is the maxim guiding all our actions. Sustainable materials, ethical production, resource-friendly value chain. Our sustainable jewelry pieces are not just beautiful; they embody genuine passion and are completely cruelty-free. Admittedly, it's not always easy for customers to discern where true sustainability gives way to mere marketing speak. We therefore rely on absolute transparency and tell our jewelry heroines everything they need to know. We avoid vague formulations: No blah-blah, no fuss, no bad vibes.

Recycled precious metals
On the way to a sustainable piece of jewelry, there are many components that lead to the best ecological and social outcome. The choice of materials is particularly important for fejn. Unlike many labels, we rely on recycled gold and silver – because there is already enough of this finite raw material in the world.
We exclusively use fine jewelry made from recycled silver and gold. Our silver jewelry is made from completely recycled 925 silver. The silver remains in its natural state or is 18-karat gold-plated. Some favorite pieces are made of solid gold – recycled and with 14 or 9 carats. We rely on recycled raw materials because conventional mining is increasingly criticized – especially in high-risk countries where child labor and permanent environmental damage can be undesirable consequences.
We use recycled precious metals for sustainable, special jewelry – at fejn.

Lab grown diamonds
Sparkling, sparklier, diamond jewelry. Gemstones crown some of fejn jewelry's pieces and are an absolute eye-catcher. They delight young and old and are an indispensable part of women's jewelry.
Our gemstones, the Laboratory Grown Diamonds, are grown in a lab. There are different methods for this. We use the so-called CVD (Chemical Vapour Deposition) method, which is particularly environmentally friendly. Through an elaborate vapor process with carbon-rich gases, a new diamond quickly grows from an existing diamond core. And the best part: the quality of cultured diamonds is just as good as that of conventional ones.

Timeless design
Our commitment to sustainability is strong and vibrant, yet it never compromises our high design standards. Clean, pure, urban: That's what fejn jewelry is all about. Whether it's a delicate silver necklace, an ornate gold ring, or pearl earrings, our jewelry becomes a cherished favorite. Thanks to the use of precious metals, it will accompany you for a lifetime, with proper care.
The sophisticated, the delicate, the urban: Our collections bear names that already reveal what you can expect from these sustainable pieces of jewelry. For instance, the individual is our collection of personalized jewelry, perfect for gifting. Behind the glamorous lies our Solid Gold Collection. Here, high-quality solid gold meets sustainable diamonds, embellishments, and other puristic styles. The the wedding collection features fejn pieces for that special day – whether you're the bride or a guest. Discover our collections and find jewelry that suits you!
And the crowning glory of our collections are our sustainable engagement rings and wedding rings, for those truly special occasions!

Fine Jewellery: A Sustainable Jewelery Choice
Sustainable to the end – that's our online jewelry shop
Rings, earrings, necklaces and co.: The fashion jewelry offering is versatile. But it's only inexpensive at first glance, contrary to common belief. Because unlike sustainable jewelry made of precious metals, fashion jewelry quickly loses its shine, tarnishes, or breaks. And then it has to be disposed of. When the next fancy event comes up, new pieces have to be bought. Such unnecessary double expenses are not sustainable at all and become a thing of the past with fine jewelry. Once purchased, it will last a lifetime with good care. Fejn's durable accessories are also timelessly designed and thus outlast every women's and men's jewelry fashion trend. Find what you're looking for and fall in love now in our online jewelry store.
