Uses & applications

Primarily used as a semi-precious gemstone for cabochons, beads, carvings, and tumbled stones. It is also used in architectural trim and as a decorative stone.

Geological facts

Named after the Unaka Range of North Carolina, USA, where it was first discovered. It is the state rock of Virginia.
