Named after Topasos Island in the Red Sea. In antique times, the name was probably used for the gemstone that is now known as Peridot. Occurs in pegmatites and high temperature quartz veins, also in cavities in granites and rhyolites. Topaz is a common gemstone that has been used for centuries in jewelry. Its golden brown to yellow color is classic but is confused with the less valuable citrine, which is sold under the name topaz. The blue topaz that is often confused with aquamarine is rarely natural and is produced by irradiating and then heating clear crystals. Topaz is the November Birthstone.
