Thorium silicate, often black, brown, or orange ('Orangite'), usually metamict and highly radioactive. It's associated with potent energy and transformation. (Primarily collector's mineral).
Black, Brown, Yellow-Orange, Orange, Reddish-Brown, Greenish, often forms prismatic or pyramidal crystals
Thorite is classified as a silicate mineral mineral which typically crystallizes in the tetragonal system. Its chemical formula is (Th,U)SiO4. Common crystal habits include in square prisms, or pseudo-octahedral crystals; also massive.
