Rubies & Sapphires

A house devoted to two stones. Sourced at origin, cut and sorted by hand, and certified by the world's leading laboratories.

The House · Since 1998

Since 1998, we have done one thing. We find rubies and sapphires of real character, follow them from the mine to the cutting wheel, and place them with the jewellers who will set them well.

Singles, matched pairs, calibrated sizes and melee. Burmese stones are offered subject to the import rules of the destination country.

From the mine to the market.

The Craft

Three disciplines, one standard

Sourcing

We buy at origin, through relationships built over years with miners and local traders. We see stones early and choose first, by hand, for clean material and honest colour.

Cutting

Each rough is studied before the wheel touches it. Our cutters bring out colour and brilliance while keeping every carat the stone allows, and calibrate to tight tolerances.

Sorting

Experienced sorters match stones by size, colour and quality, so a parcel reads as one stone repeated. Goods arrive ready for the bench.
