What characterizes sustainable jewelry?

For more and more brands, sustainability is a buzzword, for us it is the maxim to which we align everything we do. Sustainable materials, fair production, environmentally friendly value chain. Our sustainable pieces of jewelery are not only beautiful, they contain real passion and are completely cruelty free. Admittedly, it is not always easy for customers to recognize where real sustainability gives way to mere marketing talk. We therefore rely on absolute transparency and tell our jewelry heroines everything they need to know. We do without vague formulations: no blah, no fuss, no bad vibes.

Recycled jewelry and laboratory diamonds: Sustainable materials across the board

Recycled precious metals

On the way to a sustainable piece of jewellery, there are many building blocks that lead to the best ecological and social result. The choice of material is particularly important for fejn. Unlike many labels, we rely on recycled gold and silver - then there is already enough of the finite raw material in the world. Responsible jewelry also relies on sustainable gemstones. Laboratory Grown Diamonds are a good alternative with the best quality. This is behind it:

We rely on genuine jewelery made from recycled silver and gold . The silver jewelry is made from fully recycled 925 silver. The silver either remains visible or is 18-carat gold-plated. Some favorite pieces are made of solid gold - recycled and 14 carat. We rely on recycled raw materials because conventional mining is increasingly being criticized. And rightly so! The funding is an absolute CO₂ guzzler. Support for child labor and permanent environmental damage are additional unpleasant consequences. Let's end this together - with sustainable, extraordinary jewelry, online at fejn.

Lab grown synthetic diamonds

Sparkling, sparkling, diamond jewellery. Precious stones crown some pieces of jewelry at fejn jewelry and are an absolute eye-catcher. They inspire young and old and are indispensable in women's jewelry. But beautiful as they are, the dark side of gem mining is present in many minds. "Blood diamonds" - this is how diamonds are referred to, the sale of which is related to war and armed conflicts. They finance the warlords in other countries, swinging dazzlingly on the earring of women. We don't want anything, really nothing to do with it.

Our gemstones, Laboratory Grown Diamonds , are grown in the laboratory. There are different procedures. We rely on the so-called CVD process (Chemical Vapor Deposition), which is particularly environmentally friendly. A complex steam process with carbon-rich gases quickly grows a new diamond from an existing diamond core. And best of all, the quality of cultured diamonds is just as good as that of conventional ones.

Fine Jewellery: A Sustainable Jewelery Choice

Precious metals

Rings , earrings , necklaces and more: the range of fashion jewelery is varied. But, as is often assumed, it is only cheap at first glance. 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. If the next fancy event is coming up, you have to buy it again. Such unnecessary double spending is not sustainable at all and is a thing of the past with real jewelry. Once you buy it, if you take good care of it, it will last a lifetime. The long-lasting accessories from fejn are also designed to be timeless and thus outlast every fashion trend for women's and men's jewelry. Find what you are looking for in our jewelry online shop and fall in love.


Sustainability is also the focus of the packaging and shipping of our individual items. We use plastic-free organic packaging material to avoid plastic waste. Only our foam inlays of the jewelry boxes contain plastic - but this can be recycled. If you are buying more than one piece of jewellery, our zero waste packaging is a great option. The shipping of our sustainable jewelry is climate neutral. In 2021, we offset around 7.55t of CO2 with DHL Go Green alone.

Repair service

Of course, every piece of jewelry can break. This happens, for example, when a part is worn a lot, is damaged by external influences or fades due to strong exposure to the sun. Of course we are not perfect either, material defects can also happen. Whatever it is, tell us! We want to take a stand against the throwaway mentality while absolutely appreciating our high-quality materials. We are an online jeweler offering a repair service.
