Moss agate

Moss Agate is a quartz agate with impurities of manganese that form fern-like patterns that give this stone its name. Moss agate is pink to yellow-white and the "moss" is a gray-green color. Like other agates it can be displayed as a stone, a cabochon, or can be powdered and used in sleeping draughts and other potions. A typical specimen has a base value of 10gp.
