Brucite (Blue)

Brucite is a magnesium hydroxide mineral that crystallizes in the form of masses, plates, crusts, fibers, botryoidal and small tabular crystals. It can be seen in a variety of colors such as blue, green, white, yellow, pink, red, and even colorless. Brucite occurs in low-temperature hydrothermal veins in metamorphic (transformation by heat, pressure etc. ) limestone. This crystal can also occur in marble, when it is an alteration of a similar magnesium mineral known as Periclase.

Many common minerals found near or in association with Brucite include Serpentine, Dolomite, Aragonite , Calcite, and Magnesite. Brucite was first discovered in 1824 by American mineralogist Archibald Bruce. He was in his lab examining an unknown magnesium-heavy mineral from New Jersey. He realized that 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 out of Sussex County, New Jersey). Since then, Brucite can be found all across the globe, with a new deposit recently being discovered in Wadh, a town in the Khuzdar District of Baluchistan, Pakistan.

Other notable localities include Italy, Russia, Spain, the United States, Germany, Austria, China and Australia.
