Mahogany Obsidian Worry Stone

Mahogany Obsidian Worry Stone is a crystal (shop SKU HO515) on the shelves at Namaste Bookshop in Manhattan.

Obsidian is natural volcanic glass. Rainbow obsidian can show bands of color in reflected light. In crystal traditions, obsidian is associated with protection and with seeing clearly. Those ideas belong to folklore and personal practice, not to any medical claim.

Natural stones vary in color, clarity, and shape, so the piece you receive will have its own character even when the weight, grade, or size is listed.
