What is a Moonstone?
The name "Moonstone" was coined by the ancient Greeks to describe gemstones that displayed the moon's ethereal silvery light. They valued the Moonstone as a talisman for lovers. To wear it was thought to arouse the most tender of passions and true love. It was also believed that wearing the stone conveyed knowledge of future events, and could guide a person in making important decisions. The Romans thought Moonstone to be formed out of moonlight as well and to be the stone
of sensitivity and love. In India today, Moonstone is considered to be sacred and magical. It is thought to be a "Dream Stone", bringing about sweet and beautiful dreams. In the Far East, Moonstone is said to balance yin and yang and promote greater flexibility and flow with life. Moonstone amulets are tied to the ancient legends of the moon goddess of Egypt, Isis, the Greek deity, Selene and the Roman goddess of the moon, Diana.
In gemology, Moonstone is the name given to a member of the feldspar group of gemstones. They are remarkable for their chatoyancy or adularescence (glow or inner light). Fine Moonstone is highly valued and quite rare. It is found in various locales including the United States but the finest and most abundant sources are in Burma, Sri Lanka and India. Moonstone's body color can range from colorless to white,
gray, brown, yellow, orange, green, or peach. But its beauty is in its sheen, which can be white to bright blue and seems to float within as the stone is turned.The sheen effect is caused by the intergrowth of two different types of feldspar with different refractive indexes. These intergrowths result from compatible chemistries at high temperatures becoming incompatible at lower temperatures and thus a separating and layering of these two phases when the stone cools down during its genesis. The resulting shiller effect is caused by a ray of light entering a layer and being refracted back and forth by deeper layers before leaving the crystal. This refracted ray has a different character than the incident one and this produces the moonlike glow.
