Black Obsidian has been used since Paleolithic times for making tools and weapons because it holds a sharp edge. Black Obsidian Geological Description: Obsidian is a glassy, silica rich rock formed from lava with a hardness of 5 to 5.5. It is an amorphous stone meaning that its structure contains no regular geometric pattern. Obsidian is found in South America, Japan, Mexico, Afghanistan, and parts of the United States.
Obsidian is a natural volcanic glass that can be polished to a very high luster. Some stones of obsidian contain white crystals of the mineral cristobalite. When polished these stones produce a gemstone known as snowflake obsidian.he grossularite garnet used to make tumbled stones, beads and carvings is an opaque, massive garnet that often has an attractive green color. Much of it is found in South Africa where it has been inappropriately called Transvaal Jade (it is not jade and has no mineral relationship with jade).
