What is a Moonstone?
Moonstones - Stones of the Moon - Goddess Power
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 the member of a feldspar group of gemstones. They are remarkable for their chatoyancy or adularescence (Glow or inner light) Fine moonstone is quite rare and is becoming rarer everyday. 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 deep flame blue. 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.
What is it about the elusive light moving through the heart of the moonstone that captivates us?
The silver-white luster of a summer moon… the soft, mesmerizing sheen… the subtle and soothing colors…moonstones are truly nature's gift to us - meant to be worn and admired.
Moonstone Gems are a different mineral than the stones found on Cambria's beaches. Most of them come from the India and Sri Lanka area and are found in a variety of colors such as white, blue flash and rainbow.
In Cambria we have a beautiful white translucent stone on our beaches. It was named by our early settlers Moonstone after the gemstone above. It is a different mineral than the gem but it shares some of the same pale ethereal light at its center. Beach moonstones are composed of a mineral called chalcedony. The stones are formed in the earth by patient dripping of water and minerals through the ages. During storms they are swept out of their underground caves and down the streams into the ocean where they are patiently tumbled and polished by the turbulent pacific along our rocky coast.
