Obsidian cabochon


Obsidian cabochon

SKU: CA062 Category:


This obsidian cabochon was donated by Larry Bidwell and measures 30mm x 40mm. Obsidian is a black glass-like rock that forms a result of cooling volcanic lava. This obsidian cabochon is polished and convex-cut on one side and flat on the other, giving it a “domed” appearance that highlights its rich darkness. Ready for wire wrapping, setting, jewelry-making, or other lapidary or craft uses. 

100% of the proceeds from your purchase will be used to fund the Bidwell Gem & Mineral Museum. All shop items were donated by members of the Glendora Gems Lapidary Club.
