Description:Moonstone (also called rainbow moonstone) is soft milky white stone, but the most valuable variety of this Feldspar is those with a rainbow sheen. Moonstone shows a silvery or bluish iridescence, that is caused by the intergrowth of two different types of Feldspar with different refractive indexes. Moonstone was very popular with the Romans, who thought it was formed out of moonlight, also used in Roman jewelry since 100 AD. In India moonstone is considered a sacred stone to this day. This stone is from India which is a well known locality for the material. There is an array of colors (blue, gold, pink and orange) in this "Round Cabochon" cut stone. Most often, Moonstone is either carved or cabbed, so facetted stones are not as common as one might think.
