The entire fejn collection is made out of high quality precious metals.

Our solid gold jewelry is made of recycled 14K gold and embossed with the 585 stamp.

All diamonds in our solid gold jewelry are lab-grown and therewith fair and ethically sourced. Read more about that here.The stones used are valuable Swarovski circonia stones or equivalent colored glass stones.

Of course, all metals used are nickel-lead and cadmium-free and therefore allergy-friendly. You will find an exact material composition in the respective product description of your piece of jewelry.


All collection pieces are drawn up and designed in Cologne, some of them are also manufactured on site.

Additionally we work with other local businesses in Thailand who also abide by sustainability promises. Thailand is known for its great and traditional expertise in manufacturing sterling silver jewelry. So we are glad to support our local partners to preserve the artisanal jewelry knowledge and help to create more jobs.

Further all manufacturing partners are members of the Responsible Jewellery Council organization, which defines the responsible ethical, human rights, social and environmental practices that all certified RJC members must adhere to.

On top, we support our common sustainability goal by using recycled materials and compostable plastic.


We only use plastic-free organic packaging materials for shipping. In doing so, we prevent plastic waste and also concerning this area we support a sustainable lifestyle. Only the foam inlays of our jewelry boxes contain a small amount of plastic - but this material can be recycelt as well. Best is the use of the jewelry box for airtight jewelry storage, this way you avoid further waste and you are acting sustainable.

We ship climate neutral only, and were able to offset 7,55t of CO2 only with DHL Go Green shipments in 2021.
