FAQs

A black opal doublet consists of a thin slice of natural opal adhered to a dark backing material, such as ironstone or obsidian, to enhance the play of colour and provide structural stability.

Opals are traditionally set in yellow or white gold, platinum, and sterling silver, with 14ct and 18ct gold being particularly common for fine jewellery pieces.

Authentic doublets show a clear dividing line under magnification between the natural opal layer and the dark backing, and lack the uniform columnar structure often seen in synthetics.

An opal ring serves as a vibrant focal point and pairs well with minimalist gold bands or can be worn alone as a statement piece against neutral tones.

Opals are softer than diamonds and sensitive to sudden temperature changes, so they should be cleaned using warm soapy water and a soft cloth, avoiding harsh chemicals and ultrasonic cleaners.
