Crystal faces form only where there is enough open space in the rock mass to allow the natural geometric forms of the crystals to develop as free faces. When crystallization occurs, the atoms that comprise a mineral become arranged in regular, geometric patterns that are unique to the specific mineral. All rocks consist of mixtures of various crystalline minerals. When I say 'crystals,' don't visualize those beautiful pointed prisms of quartz found in geodes. This volcanic glass has an almost total absence of sizable mineral crystals within the glass matrix. Obsidian is natural glass that was originally molten magma associated with a volcano. My goal in this article is to increase your awareness of some of the more fascinating aspects of this incredible stone. The ancient volcanic hills called Glass Buttes hold a dazzling variety of gem-quality obsidian, including: mahogany, red, flame, midnight lace, jet black, pumpkin, brown, rainbow, gold sheen, silver sheen, green, lizard skin, snowflake and more. But until a few years ago when I made my first obsidian collecting trip to Glass Buttes, Oregon, I thought obsidian was pretty much just black glass. Sharp and shiny, obsidian is so different from other rocks. Ever since I had my first rock collection as a child, I've loved obsidian.
