Rough Mahogany Obsidian / 1-2" AVG - 1 LB. LOT

Obsidian is not a gemstone, but instead a kind of glass that forms when volcanic lava rapidly cools in the open air without forming any specific crystalline structures. When polished, obsidian can occasionally exhibit a gold, silver, or rainbow sheen depending on any included minerals. Mahogany obsidian’s signature brown swirls are the result of iron inclusions within the obsidian glass.
