About Opal Gemstones
Precious opals display a mesmerising play of colours on either a pale (white opal) or dark (black opal) background. Some white opals exhibit a translucent milky appearance, known as opalescence, which is separate from the play of colours.
Opals can undergo various treatments, including staining and resin impregnation, to enhance their appearance. Composite stones, such as doublets and triplets, may also be crafted from multiple pieces.
Opal Testing Methods
Differentiating natural opals from synthetic ones can be achieved through observation, refractometers, UV light, and specific gravity measurements.
Opal Symbolism and Characteristics
Opal, a birthstone for October and a zodiac gemstone for Libra, has been cherished since ancient times. The Greeks believed opals granted foresight and prophecy, while the Romans associated them with purity and hope. With a hardness of 6, opals are considered softer and more fragile than many other gemstones.
