Summary[edit]

Description
English: (12 millimeters across at its widest)

This is a synthetic gemstone called "helenite". The name is in reference to Mt. St. Helens, a stratovolcano in southwestern Washington State, USA. When heated, melted, and cooled, St. Helens volcanic ash becomes greenish-colored glass.
