Ancient monarchs treasured Opals, both for their beauty and for their presumed protective powers. They were set into crowns and worn in necklaces to ward off evil and to protect the eyesight. These gemstones were also ground and ingested for their healing properties and to ward off nightmares.
The Opal dates back to prehistoric times. It is a non-crystallized silica, which is a mineral found near the earth's surface in areas where ancient geothermal hot springs once existed. As the hot springs dried up, layers of the silica, combined with water, were deposited into the cracks and cavities of the bedrock, forming Opal. This gemstone actually contains up to 30% water, so it must be protected from heat or harsh chemicals, both of which will cause drying and may lead to cracking and loss of iridescence. Opal must also be guarded from blows, since it is relatively soft and breaks easily.
Most of the world's Opal deposits are found in Southern Australia. Other sources of this gemstone are Brazil, Mexico, Czechoslovakia and Nevada. Quality Opal is very expensive, made more so by the caution that must be exercised in cutting, polishing and setting it into jewelry.
Opals were also believed to help woman relax during childbirth. The native American Indians and the Australians Aborigines have used Opal to evoke visions and it is known as the stone of happy dreams and changes. It is thought to disperse infections and alleviate fever, purify the blood and the kidneys, regulate insulin production and improve eyesight.
