Description

Collectors say that minerals are the universe’s autobiography, written in atoms. Mandarin-orange spessartine — manganese garnet — from this famous Minas Gerais locality is among the most vivid specimens in mineralogy. The color is the saturated orange of molten glass, the luster adamantine. Collectors waited decades for material this clean.

This specimen originates from Navegador Mine, Minas Gerais, Brazil, 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.
