Topaz

Topaz is a hard, clear gemstone that is usually golden yellow but can be found in shades yellow to brown. Topaz turns pink if subjected to high temperature. Granite deposits can yield large gem-quality crystals. In the Realms, topaz was often used to create items that conferred protection from magical effects and was the preferred component when making a gem of brightness. A typical specimen had a base value of 500 gp.
