Gibbsite, also known as Hydrargillite, is an aluminum hydroxide mineral that crystallizes in the form of tabular crystals, masses, tiny concretions, and a spherical botryoidal pattern. It can be found in a variety of colors such as green, white, blue, yellow, red, and even colorless. This mineral is found in an important commercial ore, Bauxite, which is the world's main source of Aluminum and Gallium.
