SERVICE 01

Precision Cutting & Calibration

Our master cutters achieve tolerances of ±0.1mm across all calibrated sizes — from delicate 0.8mm melee to statement 10mm+ centre stones. Every stone is faceted for maximum brilliance, graded for consistency, and sorted into lots ready for immediate setting. We cut rounds, ovals, cushions, pears, marquise, emerald, and radiant cuts — plus fancy and custom shapes — in sapphire, ruby, and select coloured gemstones.

From rare Padparadscha sapphires to untreated Burmese rubies, emeralds, spinels, and tourmalines — we locate, negotiate, and deliver stones to your exact specifications, with full traceability and competitive pricing.
