About Opal Gemstones
Precious opals exhibit a vivid play of colours against a pale (white opal) or dark (black opal) background. Some white opals display a translucent milky appearance, referred to as opalescence, which is distinct from the play of colours.
Treatments for Opals
Opals can undergo various treatments, such as staining and resin impregnation, to enhance their appearance. Additionally, composite stones like doublets and triplets may be created from multiple pieces.
Opal Testing Techniques
To differentiate between natural and synthetic opals, observation, refractometers, UV light, and specific gravity measurements can be helpful.
Opal Significance and Qualities
Opal, a birthstone for October and a zodiac gemstone for Libra, has been highly valued since ancient times. The Greeks believed opals granted foresight and prophecy, while the Romans saw them as symbols of purity and hope. With a hardness of 6, opals are softer and more fragile than many other gemstones.
