Moonstone Properties

Most popular in its bluish white color, moonstone is a feldspar gemstone that looks as though it shines from within. This opalescent brilliance is called aduralescence, and occurs on account that the moonstone gemstone is made up of two minerals, stacked together in flat alternate layers within the stone. These minerals are orthoclase and albite, both of which are gemstones in their own right. When light falls through the thin layers of albite and orthoclase, the light is diffracted in different directions, giving the translucent moonstone crystal the look of glowing from within.

Moonstone History

The moonstone gemstone has been used in jewelry since antiquity. With its glowing bluish brilliance as of moonlight, moonstone reminded the ancients of the moon, thus the name given to it. Legends of Ancient Rome even spoke of moonstone as produced from the very rays of the moon solidified into rock. Accordingly both Romans and Greeks associated the moonstone crystal with their lunar deities, that is to say, the Greek goddess Artemis, whom the Romans called Diana.

Moonstone Jewelry

Moonstone was most popularly used in jewelry during the Art Nouveau period some 1,000 years ago. The moonstone gemstone remains a popular choice for jewelry to this day, especially after being made the modern birthstone for June along with pearl. Earrings, necklaces and brooches can all have moonstone in them. A moonstone gem may be set on a ring too, though care should be taken in wearing it, since moonstone is not as hard as other stones, and therefore susceptible to blows and scratches.
