Brucite groupings from Afghanistan (rare!)

Brucite is a magnesium hydroxide mineral that crystallizes in the form of masses, plates, crusts, fibers, botryoidal and small table-shaped crystals. It can be seen in different colors such as blue, green, white, yellow, pink, red and even colorless. Brucite occurs in hydrothermal veins at low temperature in metamorphic (transformation by heat, pressure, etc.) Limestone. This crystal can also exist in marble, when it is a modification of a similar magnesium mineral known as Periclase. Common minerals found near or in combination with brucite include serpentine, dolomite, aragonite, calcite, and magnesite. Brucite was first discovered in 1824 by the American mineralogist Archibald Bruce. He was in his lab to investigate an unknown magnesium-heavy mineral from New Jersey. He realized it was an entirely new piece of earth in his hands, so he chose to name it after himself (Archibald was also the first person to correctly analyze the zincite material that came from Sussex County, New Jersey). Since then, Brucite can be found all over the world, with a new deposit recently discovered in Wadh, a town in the Khuzdar district of Baluchistan, Pakistan. Other notable places include Italy, Russia, Spain, the United States, Germany, Austria, China, and Australia.
