Moonstone - Birthstone of June

Moonstone has been used in jewelry for millennia, including ancient civilizations. The Romans admired moonstone, as they believed it was born from solidified rays of the Moon. Both the Romans and Greeks associated moonstone with their lunar deities. In more recent history, moonstone became popular during the Art Nouveau period; French goldsmith René Lalique and many others created a large quantity of jewelry using this stone.

Moonstone is colourless, very translucent, or almost perfectly transparent stone, which in certain direction reflects a bluish, milky light, that has been compared to the light of the moon.

Moonstone is a potassium feldspar with white shimmer, similar to moonshine (therefore the name), called adularescence. Thin alternating layers of orthoclase and albite create the light interference in this material that is responsible for its "shiller" or "floating moon effect". Perhaps the most captivating aspect of adularescence is its appearance of motion. The misty light seems to roll across the gem’s surface as you change the viewing angle.

Moonstone can be identified by the presence of adularescence. Other gems with a similar appearance do not have the phenomenal presence of adularescence which makes identification of moonstone fairly easy. Testing for hardness is often one of the easiest methods for distinguishing moonstone from other materials. Other similar gems, such as opal, chalcedony or ammolite, are significantly harder or softer than moonstone. Top quality moonstone can show an incredible "three-dimensional" depth of colour, which no other gemstone can replicate, making moonstone almost unmistakable.

Generally, the more transparent and colorless the body and bluer the adularescence, the higher the moonstone value.

Moonstone is always cut either in cabochon or with a plane surface, never with facets.

Moonstone gemstones are not treated or enhanced.

Important deposits of Moonstone exist in India, Sri Lanka, Myanmar (Burma), Australia, Madagascar, Tanzania, and Brazil.

Moonstone is the adularescent variety of orthoclase feldspar and has a lot of “relatives”, such as labradorite, rainbow moonstone (which is labradorite too), sunstone… The color of the orthoclase may be white, beige, brown, red-brown, greenish, or yellowish and pretty often these minerals are called moonstone too, what is not completely correct.

Moonstone is a master healer for women - it brings soothing, healing calm energy and helps regain back your power and inner balance. Moonstones encourage hopes and dreams.

Moonstone benefits feminine reproductive systems, improves fertility, encourages hormonal balance. Moonstone powers have beneficial effects during pregnancy and childbirth. Moonstone powers may encourage a healthy growth rate in children and teenagers and combat aging in elderly people. It also helps relieve insomnia while encouraging pleasant dreams.
