Description

The rarest things on Earth were formed by the most ordinary processes, repeated for eons. Labradorescence — that ghostly play of blue, green, and gold — occurs when light diffracts between ultra-thin feldspar layers deposited during slow magmatic cooling. Each specimen is a prism masquerading as stone. Turn it in sunlight and it remembers something ancient.

This specimen originates from Labrador, Canada, 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.

Locality

Labradorite Freeform from Labrador, Canada. This locality is known for producing specimens of exceptional quality.

Collector Notes
