Topaz is a silicate mineral containing aluminum and fluorine. Without impurities, topaz is colorless and transparent. However, it is often found colored due to various impurities such as iron, titanium, chromium and vanadium. The most common colors of such topazes are blue, brown, orange, yellow, green and pink.
