About Natural Rainbow Moonstone :-Rainbow Moonstone is a colorless to milky white colored, semi-precious gemstone from the Feldspar mineral family which is recognised for its beautiful shimmering effect, better known as 'Adularescence'.Moonstone has translucent white color with a white sheen similar to "moonshine" that rolls or flows over the stone when rotated, hence the name "moonstone." The sheen is caused by light diffraction within layers of feldspar. Generally a creamy translucent white stone, rainbow moonstone features occasional iridescent or multicolored (especially blue) flashes with transparency that ranges from opaque to semitranslucent. Rainbow moonstone is best seen in natural light for play of color. Moonstone has been used in jewelry going back to ancient civilizations. The Romans believed moonstone was born from solidified rays of the moon. The Greeks and the Romans associated moonstone with their lunar gods. During the Art Nouveau period in the early 20th century, moonstone became popular with artists and goldsmiths for creating jewelry.
