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.

Obsidian Color & Occurence
Pure obsidian is a very dark color. It gets this color from the presence of iron and magnesium. Colorless obsidian is rare. Mahogany obsidian has dark-brown to black and red banding. Sheen obsidian is dark-brown to black with a golden or silver sheen (this is also called aventurescence). Rainbow obsidian is dark-brown to black with an iridescent sheen. The iridescence of obsidian can be gold, silver, blue, violet, green or combinations of these colors. The rainbow colors of rainbow obsidian come from the presence of augitic pyroxene. "Fire" or "flame" obsidian reflects bright colors due to the presence of nanometric magnetite crystal layers. Transparent pale yellow-green to brownish obsidian from Peru is referred to as macusanite. Translucent to opaque, black-streaked orange, red or brown obsidian nodules from the American Southwest are known as "Apache tears". Orange obsidian is referred to as "pumpkin obsidian" and plum-colored obsidian is called "plum obsidian".
