5.02 ct Bi-Color Sapphire — Unheated | Collector Grade

$27,500.00

A masterpiece of living color. This 5.02 carat unheated sapphire shifts through a mesmerizing spectrum — from deep oceanic blue to vivid teal and lush green — transforming with every movement of light and change of angle. Its bi-color zoning and strong pleochroism give rise to a natural color-change effect, revealing entirely new personalities under daylight, shade, and incandescent light alike.

Expertly faceted in a precision cushion cut, the gem’s facets create endless refractions of tone and fire, emphasizing the dual nature of its hue. Completely untreated and certified by Bellerophon Gemlab Paris, this sapphire embodies geological artistry at its purest — formed over millions of years through the Earth’s own metamorphic and basaltic forces, untouched by human alteration.

This is a sapphire meant for the discerning few — a stone that feels alive, ever-changing, and beyond classification.
