Brucite is a magnesium hydroxide mineral that forms in a variety of habits, commonly discovering light-colored, transparent to translucent crystals with a pearly to vitreous lustre. It can occur as tabular or prismatic crystals and may display fibrous or massive aggregates, often developing on hydrothermal or serpentinized rocks. In hand specimens, brucite presents as white to colorless crystals or masses, occasionally tinted by impurities, and it is prized for its delicate transparency and clean, glassy surfaces.

Brucite from Wood’s Chrome Mine, Lancaster County, Pennsylvania, USA
Wood’s Chrome Mine is the classic American locality for crystallized brucite. Its best specimens are not merely “old Pennsylvania” curiosities; they are benchmark brucites: pale, lustrous, translucent plates and rounded aggregates that sho…Read guide

Brucite from Killa Saifullah District, Pakistan
Brucite from Killa Saifullah, Pakistan: saturated lemon-yellow color, translucent botryoidal forms, and formation as an alteration product in serpentinite.Read guideAbout Brucite
Notable localities include Pakistan, South Africa, the United Kingdom, the United States, and Australia, where brucite often forms in serpentinite belts or skarn environments associated with magnesium-rich rocks. Some specimens occur as associated minerals in CO2-rich hydrothermal systems, and finer crystals can be unearthed from cleft pockets where secondary mineralization has occurred. Collectors value brucite for its subtle coloration, reflexive luster, and the way thin, perfect crystals can reflect light in small cabinet displays, as well as for its crystallographic simplicity which makes it a good reference for habit and perfection in magnesium hydroxide minerals.
