Obsidian is naturally occurring volcanic glass which has been used as a gemstone since antiquity. Obsidian was named after Obsius, a Roman who discovered a similar stone. Obsidian forms when lava cools and whilst it is mineral-like, it is not considered to be a true mineral because its composition is too complex and it does not have a crystalline structure. In addition to its decorative use, obsidian has a practical use. Due to its lack of cleavage, conchoidal fracture and acute edges when broken, it has been used to make smooth and sharp surgical scalpel blades. Obsidian has been used to make arrow heads and blades, as well as ornaments for thousands of years by people such as the pre-Columbian Mesoamericans and the ancient Egyptians.
