About Opal Gemstones

Precious opals are cherished for their striking play of colours set against a pale (white opal) or dark (black opal) backdrop. Some white opals exhibit a translucent, milky appearance, which is referred to as opalescence and is distinct from the play of colours.

Opal Treatments

Opals can undergo various treatments, such as staining and resin impregnation, to enhance their appearance. Additionally, composite stones like doublets and triplets can be crafted from multiple pieces.

Opal Testing Methods

Techniques such as observation, refractometers, UV light, and specific gravity testing can be used to differentiate natural opals from synthetic ones.

Opal Symbolism and Properties

Opal is both an October birthstone and a Libra zodiac gemstone, holding symbolic significance throughout history. Ancient Greeks believed opals endowed the wearer with foresight and prophecy, while Romans considered opals to be symbols of purity and hope. With a hardness of 6, opals are among the softer and more delicate gemstones available.
