FAQs

Opal and diamond cluster designs gained immense popularity during the Victorian and Edwardian eras, where opals were prized for their play of colour and diamonds provided a bright contrasting border.

These pieces are traditionally crafted from yellow or white gold, housing natural opals surrounded by melee diamonds set in precious metal prongs.

Authentic pieces typically feature hallmark stamps indicating metal purity, natural inclusions within the gemstones, and traditional claw or grain setting techniques characteristic of historical periods.

An opal pendant pairs well with minimalist necklines to allow the play of colour to stand out, and can be layered with finer chains for a contemporary look.

Opals contain water and are sensitive to extreme temperature changes and harsh chemicals; they should be cleaned gently with a soft cloth and stored away from direct sunlight.
