- Fascination Gemstones -

The love story of gemstones and jewelry has been going on for thousands of years.

Cutting a million-year-old gemstone, shaped by nature, into a sparkling gemstone is a fascinating process. This craftsmanship brings out the beauty of nature, while each stone tells its own story. It is always a great feeling being able to work with such beautiful and rare gemstones.

"Quality makes the difference"

For our customers, we try to find beautiful colored gemstones over the whole world. The high level of our stone quality is based on professional expertise, a 50 years experience and passion, as well as a worldwide network to the best resources that has grown over generations.

Thereby the compliance with quality guidelines, such as: Selection of raw materials, cut, shape, proportion, color, transparency and polish, is a crucial component.

Due to increased treatment methods in recent years, the testing of authenticity and naturalness has become more important than ever. Therefore, we work closely with the German Gemmological Society and its Foundation for Gemstone Research (DSEF) for certification.
