Quartz

Quartz is one of the four classes of gemstones used in Stone Casting. There are four different types of quartz: Agates, Amethysts, Plasma Quartz, and Rose Quartz. Each of them are relatively similar in power, with the exception of Plasmas (due to their malleability). That said, an agate and rose quartz are about the same power level if both gems are the same size.

An interesting challenge with quartz comes from their natural shapes. Naturally grown in sharp edges and jaged lines, ingestion of Quartz are often marred with injury. Due to the necessity of their use by apprentice Stone Casters, Quartz class gemstones are often referred to as the "bleeding stones".
