The moonstone gem stone resembles a pearl so much that the two stones are both the birth stone of the month of June. The moonstone bead is so known because its opalescence sometimes resembles moonshine. The moonstone bead has a blue or white gloss and is made of substances known as orthoclase feldspar and albite. The moonstone gem stone occurs naturally across the globe -- from Germany, India, Brazil, Mexico and even the United States. Like the traditional blue/white moonstone, you can find a green moonstone, peach moonstone, rainbow moonstone and more. Browse our moonstone collection below.
