Moonstone

Moonstone mineral specimen

Moonstone is the birthstone for the month of June and the stone traditionally given in celebration of the 13th anniversary of marriage. Moonstone has always been very popular in India. The stone was also prized by the Romans, who thought it was magically formed out of moonlight. Moonstone was used in Roman jewelry since the year 100 AD. Ancient Greeks and Romans both linked the stone with the moon deities. Moonstone comes from the mineral family feldspar, which is one of the most plentiful in the world, however fine gem quality moonstone is scarce and is becoming more scarce as time goes on. Moonstone was very popular in the Art Nouveau jewelry of the early 20th century and continued to flourish until around 1925 in the US. Men wore the stones in stickpins for their ties, in cuff links, rings and mounted as ornaments on watch chains. Women wore moonstones in bracelets, brooches, rings, earrings and necklaces.

Moonstone rates a 6-6.5 on the hardness scale. It is a relatively soft stone but given the proper care, it can last a long time. Moonstone is whitish, gray-white, silvery-white, or milky white with a soft blue shimmer that moves across its face as the stone is moved. This blue moving light is called adularescence. The more shimmer the stone has, the more valuable it is. If the shimmer is of other colors besides blue, the stone is called a "rainbow moonstone." This distinctive and magical shimmer is actually caused by tiny albite inclusions that reflect and scatter light, mimicking the moon's glow, hence the gem's name.
