Calcite is a beautiful mineral that comes in many colors like white, orange, and green. It can be found in caves, mountains, and even in the shells of tiny sea creatures.
The Calcite is an incredibly diverse mineral, often appearing as colorless or white crystals, but can be found in almost any color of the rainbow. It frequently forms distinctive rhombohedral shapes or can grow into impressive cave formations like stalactites. Its perfect cleavage often results in smooth, flat surfaces.
