How do I care for an opal ring?

Opals contain water within their structure and possess a moderate hardness, making them sensitive to sudden temperature changes, harsh chemicals, and physical impacts. Clean your jewellery gently with a soft cloth and warm soapy water, avoiding ultrasonic cleaners and prolonged immersion.

What is the difference between solid opal and a doublet?

A solid opal consists entirely of natural opal material cut from the rough stone. These stones display a natural body tone and depth. A doublet layers a thin slice of genuine opal over a dark backing layer, which deepens the visible colours while providing structural support.

How can I tell the period of an opal piece?

Dating relies on a combination of metal purity hallmarks, gemstone cutting styles, and the overarching design characteristics of the setting. Victorian and Edwardian pieces often feature detailed hand-work and lower-visibility claws, while mid-century designs frequently utilise cluster halos and distinct basket mounts. Examining the construction under magnification reveals the hand-fabrication methods typical of earlier eras compared to later manufacturing.

Are all opals Australian in origin?

While Australia supplies a vast proportion of the world's precious opals, including notable black opals and boulder opals, stones are also mined in other global locations. Specific regional sources such as Coober Pedy are sometimes documented in historical records or modern certificates accompanying the jewellery.
