Topaz is yellow quartz, and you may have seen it in your grandmother's beaded jewelry.

Topaz can mean a type of mineral that is found in many different colors. It can also specifically mean yellow quartz that is also called imperial topaz, common topaz, or false topaz. Topaz is often used in necklaces, earrings, and other types of jewelry. Chances are you've seen a woman wearing topaz at some point. This type of topaz is common and not as precious as some other types of gems such as emeralds or rubies. Still, most would consider topaz pretty.
