PRECIOUS STONES

Emeralds, rubies and sapphires, selected in Geneva

Precious stones have been at the heart of the Ultraco family business for five generations. From our office at the heart of Geneva, we select Colombian, Zambian and Sandawana emeralds, as well as Burmese rubies and sapphires, for collectors, royal families, jewelers and private clients.

A fine gemstone is chosen in person. Colour, clarity and brilliance can only be judged in natural light, with the stone in your hand. This is why we present our stones privately, by appointment, rather than online.

What we offer

• Loose emeralds, rubies and sapphires of exceptional quality, with gemmological certificates when available
• A search for a specific stone through our sourcing service
• Bespoke jewels designed around your stone, see our jewelry collection
