Etymology

Tounkite is named after the Tunka Valley, the location where it was first discovered. The name reflects the mineral's place of origin and is not associated with a person or historical figure.

How to recognize it

Tounkite can be identified by its hexagonal crystal habit and colorless to white color. It has a hardness of 4 to 5 on the Mohs scale, which is relatively soft, and a vitreous luster.
