Description

Consider what had to happen for this specimen to exist. Kornerupine is a collector’s gem — rarely seen in jewelry, spectacular in a collection. The brown-green color changes to reddish in incandescent light. Mogok produces the finest material. The mineral was named after Danish geologist Andreas Nikolaus Kornerup in 1884. Fine facetable crystals are genuinely rare.

This specimen originates from Mogok, Myanmar, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.

Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.

Formation

This specimen formed through geological processes operating over timescales that dwarf human history. The specific combination of chemistry, temperature, pressure, and time at this locality produced material of exceptional quality that makes it a valued addition to any serious collection.
