Obsidian is naturally occurring volcanic glass. It has been used as a gemstone since antiquity. It was named after Obsius, a Roman who discovered a similar stone. Obsidian forms when lava cools. Even though 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. Obsidian is not only used for decorative purposes, it also 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 the pre-Columbian Mesoamericans and the ancient Egyptians. The snowflake appearance comes from cristobalite crystal inclusions.
Obsidian is not usually treated or enhanced.
