Adamite, or hydrous zinc arsenate, was named for French mineralogist Gilbert-Joseph Adam (1795-1881). The crystals may be found in many colors, but commonly range from yellow to green. It is a fairly rare mineral and not of gem quality.
Adamite is capable of correcting imbalances of the heart over the intellect. If you feel you are excessively ruled by your emotions, adamite can be of great use to you. It also provides inner strength during stressful, emotional times and allows you to properly express how you are feeling.
