Topaz Jewelry Directory
Topaz is a Silicate Mineral. The gems can be opaque to transparent/translucent. Pure Topaz is colorless and transparent but is usually tinted by impurities. Blue and pink are rare in natural form. Typically, topaz is wine, white, reddish-yellow, pale green, gold, reddish-orange or blue-brown. Heat treatment is used on pale-yellow and gray, which intensify the mineral, to produce a fine, vivid blue-colored gemstone.
