Precious Stones

Rubies, sapphires, emeralds

We use our expertise, our lapidary facilities and our privileged contacts to reliable sources in Burma, Kashmir, Sri Lanka, Cambodia, Thailand, Madagascar and Colombia to make truly precious stones available, selected by our specialists' initiative or upon specific customer requests.

For pre-examination, the Lausanne Center can supply by e-mail pictures and specifications of suitable stones from our stock.

Large high-quality gems come with certificates by internationally recognized laboratories. Calibrated stones are guaranteed within narrow and consistent tolerances.

Our gemologists and market experts are available for professional advice. They also make valuations for insurance purposes, legacies and inventory transfers, or submit individual purchase offers.
