1.5" Mahogany Obsidian Worry Stones

Worry stones are smooth, polished stones, usually in the shape of an oval, with a thumb-sized indentation. They are often used by people for relaxation or anxiety relief purposes, the same way as some people use a fidget spinner. Typically, worry stones are 1 1/2 to 2 inches across. They may also be referred to as palm stones, thumb stones, fidget stones, etc.

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.
