Rainbow Moonstone, also known as White Labradorite, is actually a variety of Labradorite that exhibits flashy colors and rainbows throughout. The name “Rainbow Moonstone” was coined by the lapidary and mineral communities to describe this stone, even though it’s not an Orthoclase (Moonstone). Rainbow Moonstone deposits can be found in Sri Lanka, Australia, Mexico, Madagascar, Poland, and India.
Named for its moon-like sheen, Moonstone is a Feldspar mineral exhibiting a soft, watery opaqueness and a silvery-white reflection called chatoyancy that moves as a line across the surface as light varies. Moonstone occurs in delicate shades of peach, blue, gray, white and a prismatic variety known as Rainbow Moonstone.
