The origin

Gems have always caught people’s attention with their radiant beauty and mysterious magic. Us too!
Therefore, we spend much of our time tracking down these unique treasures and natural artwork. The search for high-quality gemstones often takes us to remote corners of the earth, not only when a significant new discovery is suddenly reported somewhere and a quick response is needed, but also to regularly visit the well-established discovery-areas, mines, and trading venues. These often challenging trips are required to get special on-site information and news. We also focus on maintaining already existing contacts as well as building new ones, deepening trust and consolidating these connections over years of cooperation. The inconvenience of traveling in partly inhospitable areas is compensated by unforgettable experiences and unique encounters with the local people. They hold in their hearts the same passion for these wonderful treasures of our Mother Earth as we do.

The processing

All acquired stones, whether raw or already grained, are personally examined and tested to decide their purposes. Raw pieces and crystals that have a unique character from their natural appearance are expertly cleaned and reserved for connoisseurs and designers who enjoy such special gemstones.
The other raw ones are sorted according to size, color, and purity, and then examined carefully, especially regarding their further treatment. We also check already polished stones to see if there are any minor flaws which can be remedied, or if there is a need for our hand-picked specialist to improve upon the polish. Every gemstone grinder has special areas and techniques as well as their own style and personal signature. Only the right interaction of artist and stone can create unique, polished gemstones and bring their inherent colors to full light.
Subsequently, the individual stones thus obtained are examined and evaluated again, so we can finally put together precisely balanced color sets and entire layouts for necklaces and bracelets.
