Brucite is characterized by its platy or fibrous crystals, and is often colorless or white, but may appear in other colors such as light blue, green, or gray due to iron or manganese impurities. Brucite is usually found in metamorphic rocks such as serpentinite marble, and in veins of basaltic lava.
