Obsidian is volcanic glass, considered a rock rather than a mineral. It is formed in the last stage of basaltic eruptions, when the silicas, left over after most other elements have been used up, are ejected and chilled at surface temperatures. Rainbow obsidian has a multicolored iridescence.
Derived from "tapaz," the Sanskrit word for fire, topaz is one of the most brilliant cut gemstones in existence. Topaz comes in a variety of colors from yellow to blue, and deeper blues and pinks are often created by heat-treating stones. Brazil is the world's top exporter of topaz.
