Topaz Description
Topaz actually has an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple. Colorless topaz is plentiful, and is often treated to give it a blue color
Topaz History and Lore
Most authorities agree that the name topaz comes from Topazios, the old Greek name for a small island in the Red Sea, now called Zabargad. (The island never produced topaz, but it was once a source of peridot, which was confused with topaz before the development of modern mineralogy.)
