Stones on request
Looking for a particular stone? We search for it through our international network of mines and dealers, have it certified and bring it to Geneva for you to see.
How we buy
We are always in touch with mines and dealers around the world. Thanks to this network, we can often bring the stone you are looking for to Geneva within a few days.
We buy directly from miners, cutters and dealers in Sri Lanka, Colombia, Madagascar, Mozambique and Zambia, from partners we have known for more than twenty years. In Myanmar, historically the most prestigious source of rubies, trusted partners of more than twenty years give us access to its stones. Buying close to the producers means fewer intermediaries and fairer prices for you.

At the source
For decades we have travelled to the mines and markets where stones are found, cut and traded.
We only sell natural, untreated precious stones, appraised by us and certified by third-party, internationally recognised laboratories.
