Description

There are objects in this world that carry the weight of unimaginable time. Schorl is the most common tourmaline, yet these striated black prisms from Namibia’s Erongo region are exceptional — sharp terminations, lustrous faces, and often perched on clusters of smoky quartz in a composition nature arranged over millions of years.

This specimen originates from Erongo Mountain, Namibia, 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.
