What is White Moonstone?
A well-known member of the feldspar group, white Moonstone is renowned for its shimmering white luster; in fact, the ancient Romans believed this stone to have been formed from solidified moonlight. Although it is the state gemstone of Florida (to honor the Apollo moon landings), it is not actually found in that state.
