Huge, 7.4" Polished Mahogany Obsidian Sphere - Mexico
This is a huge, 7.4" wide mahogany obsidian sphere, collected from Mexico. This obsidian specimen has been polished, revealing the swirls and streaks of red/orange color that give this form of obsidian its name.
Mahogany obsidian is a natural glass formed when lava cools very quickly during volcanic eruptions. Because the speed at which the lava cools, no crystal structures can form. The red streaks in the normally jet-black obsidian are caused by hematite or other iron-based mineral inclusions. This stone can be found worldwide, though most comes from Mexico.
