Why Precision Cutting?

When a gemstone is called “precision cut,” it means every facet has been carefully planned and polished with accuracy, using high-precision faceting equipment. The goal isn’t just to shape the stone, but to make sure light travels through it in the best possible way — bringing out maximum brilliance, colour and symmetry.

Unlike many commercial cuts, which prioritise weight retention or speed, precision cutting gives priority to beauty above all else. Well-proportioned angles, crisp facet junctions and perfect symmetry allow the gem to sparkle evenly and reveal its true character.

For collectors and jewellers, this means a stone that feels harmonious and alive in the hand — balanced, bright, and finished to a higher standard.
