Obsidian
Glossy black volcanic glass with a deep, mirror-like shine. Some pieces show a faint sheen or smoky brown tones when held up to strong light.
About obsidian
Obsidian is natural volcanic glass. It forms when lava cools so quickly that crystals have no time to grow. It breaks with very sharp edges, and was used for blades and arrowheads. Pliny the Elder linked its name to a Roman called Obsius.
Obsidian is traditionally known as a strongly protective stone. Crystal tradition says it shields against negativity and helps you face hard truths, and it is often linked with grounding and clearing away what no longer serves you.

Keep Obsidian by the front door, on a desk near screens or in a pocket for protection. Many people hold it during meditation to feel grounded.
Care
Obsidian is glass and can chip if dropped, leaving sharp edges. Wash with lukewarm soapy water and dry with a soft cloth. Store apart from harder stones.
