A generous 1KG bag of natural Black Obsidian rough, ideal for wholesale buyers, crystal retailers, healing practitioners, and collectors. Each bag contains approximately 15–25 pieces ranging from 2–3cm in size, though this may vary due to the natural formation of the stone. Black Obsidian is a powerful volcanic glass formed when lava cools rapidly. Known for its grounding and protective properties, it is widely used in energy work, meditation, and sacred space cleansing. Its natural sharpness has also made it a historically significant tool-making material. Sourced for quality and consistency — perfect for resale, bulk gifting, or stocking a crystal shop.
