description Prase Overview
Prase is an opaque, leek-green variety of quartz whose color comes from inclusions, commonly chlorite or actinolite. It differs from prasiolite, a transparent green form of quartz whose color is generally associated with heat treatment or other color-producing processes. Prase is collected as a mineral specimen and used as a gemstone, although its opaque appearance distinguishes it from clearer quartz varieties.
