How to Care for Your Gold Opal Jewellery — What's Different from Silver

Caring for Gold Opal Settings — What's Different

Most opal care advice focuses on the stone itself — avoiding water, chemicals, and impact. But when your opal is set in gold rather than sterling silver, the metal itself requires slightly different consideration. Here's what to know about keeping your gold opal jewellery looking its best.

9ct vs 14ct vs 18ct Gold — What It Means for Care

Gold jewellery is measured in carats (not to be confused with gemstone carat weight). The carat rating tells you what proportion of the metal is pure gold:

• 9ct gold — 37.5% pure gold, the rest alloy metals. More durable and scratch-resistant, slightly less yellow than higher carats. Most of our gold opal pieces use 9ct or 14ct.
• 14ct gold — 58.3% pure gold. Richer colour, still very durable for everyday wear.
• 18ct gold — 75% pure gold. Richest colour, softest, requires more careful handling.

Lower carat gold is actually more durable for daily wear precisely because the alloy metals add hardness. For opal settings — where protecting the stone is the priority — 9ct and 14ct gold strike the right balance.

Cleaning Gold Opal Settings

The opal care rules still apply: no ultrasonic cleaners, no steam, no harsh chemicals. For the gold setting itself:

• Use a very soft toothbrush with warm (not hot) water and a tiny drop of mild dish soap to gently clean the setting
• Work around the opal rather than on it, keeping the stone as dry as possible
• Rinse with clean water and dry immediately and thoroughly with a soft cloth
• Polish the gold setting gently with a jewellery polishing cloth designed for gold

Rose Gold — A Special Note

Rose gold gets its warm pink colour from copper in the alloy. Copper can tarnish slightly over time, particularly if the piece is regularly exposed to moisture or sweat. This is normal and a gentle polish with a gold jewellery cloth restores the colour beautifully. Our rose gold pieces — like 'Ellis Flame' and 'Gundabooka Glow' — are 9ct solid rose gold, not plated, so they can be polished and maintained indefinitely.

White Gold — Rhodium Plating

White gold is naturally a pale yellow-grey colour. To achieve the bright white look, white gold is typically rhodium-plated. This plating can wear over time with daily wear, revealing the slightly warmer tone beneath. Replating by a jeweller every few years (if needed) restores the original finish. Our 9ct white gold pieces hold their finish well with normal care.

Storing Gold Opal Pieces

Store gold opal jewellery separately from other pieces to avoid scratching both the gold and the opal. A soft-lined box with individual compartments is ideal. Remove before sleeping — gold settings can catch on bedding and the repeated pressure isn't ideal for the opal.

With these simple habits, your gold opal jewellery will remain as beautiful as the day it arrived.
