How do I care for gold opal jewellery?

Opals contain water and require gentle handling away from harsh chemicals, ultrasonic cleaners, and extreme temperature changes. Clean them simply with a soft, damp cloth. Store pieces individually in padded boxes to prevent scratches from harder gemstones like diamonds set alongside them.

What is the difference between solid and boulder opals?

Solid opals consist entirely of precious opal material, whereas boulder opals retain a portion of their natural ironstone host rock. The attached ironstone often provides natural reinforcement and deep background contrast. Both forms utilise eighteen-carat or nine-carat gold settings depending on the era of manufacture.

How can I date an opal ring?

Stylistic cues such as Victorian multi-gemstone arrangements or Edwardian drop ball motifs offer initial chronological markers. Hallmarks stamped into the gold band provide specific assay office and date letter details. Mid-century pieces from nineteen-fifty often favour cleaner lines and distinct cluster formations in eighteen-carat or fourteen-carat yellow gold.

Are these opals natural?

The inventory includes natural opals, black opals, and boulder opals sourced from locations such as Australia. Descriptions specify the exact stone variety present in each item. Doublets also appear, utilising a thin slice of natural opal bonded to a supportive backing material.
