Malachite (NWN)

Favored by druids for its graceful and natural beauty, malachite is known for its strikingly ornamental bands of light and dark green that alternate throughout the entire stone. Painters have also been known to crush the gem and use it as a pigment. Adventurers have also discovered that the gem bubbles and dissolves readily in acid, making is an effective - if expensive - means or identifying certain dangerous substances.
