Black Obsidian 4mm round bracelet, ethically sourced from Oregon, USA. Natural Black Obsidian. 
 
A natural volcanic glass, Obsidian is formed by the rapid cooling of volcanic magmas. Typically jet black, this igneous rock also comes in many varieties such as mahogany, snowflake, sheen, spider web, and rainbow. Obsidian’s conchoidal fracture makes it easily chipped to form razor-sharp edges. It was used by many ancient cultures to make weapons, tools, and ornaments.
 
Obsidian is used for protection and the releasing of negative energy. A stone for power, protection and grounding. Keeps you tethered to the here and now and feeling and sense of strength and inner confidence.
 
Strung on elastic cord to ensure the perfect fit for anyone.
