Handcrafted custom jewelry

With a large variety of precious stones and gold alloys, the jewelry by Leni is fine and elegant. The designs are handcrafted in the goldsmiths atelier of Adam Uhren Bijouterie in Switzerland and can be customized as desired. In this way, all work steps can be monitored and fair working conditions guaranteed.

Recycled precious metals and Swiss precious stones

The gemstones are collected on mineral excursions with gemstone experts in the Swiss Alps. The products also bear the Oekogold label. This means that the precious metals come from a source that is certified by the Responsible Jewelery Council (RJC) in London. The certificate guarantees the exclusive use of recycled precious metals and thus prevents mining.

Tradition since 1935

Leni belongs to the third generation of Adam-Uhren Bijouterie, which has been run as a family business since 1935. The preservation of craftsmanship and tradition are very important here. The Swiss gemstones also tell the story of the Swiss Alps and the people who carefully find them.
