Snowflake Obsidian 12mm Round Beads - Grade B

3 items left

These 12mm smooth round natural snowflake obsidian gemstone beads are mostly well shaped. I'm grading them as B because the strand contains too many beads with little to no patterning from the white cristobalite crystals. A bead or two may actually be a brown obsidian or may have a chipped/broken drill hole.

Obsidian is not a mineral (no crystalline structure) but a volcanic glass formed during rapid cooling of silica-rich volcanic lava.
