Opal is an amorphous stone that provides the gem with a unique play of light and colors. The most highly prized stones will display the strongest effect of colors. It occurs in nature in volcanic rocks, cavities or cracks in silica-rich rocks. Due to the great demand, synthetic opals are being produced today with similar appearances and physical properties (see: Opalite).

The name Opal is derived through the Greek opallios, from the Sanskrit Upola, meaning “precious stone”.
In the Bible it is called “Leshem”, one of the Breastplate Stones of the High Priest, identified with the Dan tribe.
Ancient cultures of the East gave the gem religious and mystical significance – ‘The God’s Stone”. Indian tribes saw it as the vision stone of the tribe’s healer, while in other places negative superstitious beliefs were attached to the stone believing that it could affect the fortune and temper of the person wearing it.

The Opal is a sensitive stone and should be kept in moist environment far from acidic substances- soap, creams perfumes etc.

Today also, the stone is regarded as having mystical as well as medicinal properties. It enriches the imagination and creativity, sharpens intuition and stimulates inspiration. It enhances memory, is good in treating eye and digestive system diseases as well as helping in childbirth.
The stone strengthens personal and business relationships and can help overcome difficult feeling states of depression and desperation. It stimulates love and passion, and encourages spontaneity.
