About Opal Gemstones
Precious opals are known for their vibrant play of colours against a pale (white opal) or dark (black opal) backdrop. White opals may exhibit a translucent, milky quality, which is referred to as opalescence, separate from their play of colours.
Opal Treatments
Opals can undergo a range of treatments, such as staining and resin impregnation, to enhance their overall appearance. Additionally, composite stones like doublets and triplets can be created from multiple pieces.
Techniques for Opal Testing
Differentiating natural opals from synthetic ones can be achieved through various methods, including observation, refractometers, UV light, and specific gravity testing.
Opal Symbolism and Properties
Opal is an October birthstone and a zodiac gemstone for Libra, carrying historical and symbolic significance. Ancient Greeks believed opals granted powers of foresight and prophecy, while Romans considered opals as symbols of purity and hope. With a hardness of 6, opals are among the softer and more delicate gemstones available.
