Brucite

This brucite formed through the alteration of magnesium-rich rocks during low-temperature metamorphic and hydrothermal processes deep within the mountains of Balochistan. As mineral-bearing waters interacted with ultramafic host rock, layers and crystal masses of brucite slowly developed within fractures and open spaces.

Specimens from Pakistan are especially valued for their bright coloration, silky luster, and unusually well-formed crystal aggregates. Depending on trace elements present during formation, brucite from the region can display vivid yellow tones and a soft pearly appearance that catches light across the crystal surfaces.

Light in texture yet striking in color, this specimen reflects the unique mineral chemistry and mountainous geology that make northern Pakistan one of the world’s great mineral-producing regions.
