Topaz occurs in a wide range of colours that as well as 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. Imperial Topaz with its distinct peach, pink, orange (as in this example) or champagne hues, is the rarest variety of Topaz. Topaz is pleochroic, meaning that the gem can show different colors when viewed from different directions. Topaz is a birthstone for November. Weight: carats Origin: unknown Crystal structure: orthorhombic Composition: aluminium fluorohydroxysilicate Mohs hardness: 8
