Topaz is often confused with the less valuable citrine. Topaz is a very hard gemstone but it can be split with a single blow, a trait it shares with diamond. Any Topaz labeled with a prefix name (such as Gold Topaz, Madeira Topaz, False Topaz, Brazilian Topaz, Bahia Topaz, and Citrine Topaz) is heat-treated Citrine.
