A member of the Feldspar Group, Moonstone is a potassium
feldspar of the orthoclase (adularia) species. The stone has a shimmering white affect that resembles
moonshine, and this is probably why it's commonly called Moonstone. It has a vitreous luster and can be
sensitive to pressure. It's a common gemstone used in jewelry as cabochons. Can be found with a
cat's eye affect occasionally.
Deposits are obtained from Brazil, India, Sri Lanka, Myramar (Burma), Madagascar and
the United States.
