About Opal Gemstones

Precious opals exhibit a striking play of colours on a pale (white opal) or dark (black opal) background. White opals, in particular, may display a translucent, milky appearance known as opalescence, which is distinct from their play of colours.

Treatments for Opals

Opals can undergo various treatments, such as staining and resin impregnation, to enhance their appearance. Composite stones, like doublets and triplets, can also be created using multiple pieces.

Methods of Opal Testing

Various techniques, including observation, refractometers, UV light, and specific gravity testing, can help distinguish natural opals from synthetic ones.

Symbolism and Properties of Opals

Opal is an October birthstone and a zodiac gemstone for Libra, carrying historical and symbolic significance. The ancient Greeks believed opals bestowed powers of foresight and prophecy, while Romans regarded opals as symbols of purity and hope. With a hardness of 6, opals are among the softer and more delicate gemstones available.
