COLOUR

A light, luminous sky blue of medium tone with even saturation and a cool, crystalline brilliance — an open, approachable hue that reads bright in daylight and gentle under lamplight.

INCLUSIONS

Healed fractures with straight twin lamellae, fine particulate clouds and occasional crystal inclusions — the natural signatures of corundum, regarded as characteristic features rather than flaws.
