Opals are unlike any other gemstone—alive with shifting color, full of mystery, and sensitive to the touch of time. Their dancing hues can mirror sunrise, stormlight, and the ocean’s depths, yet beneath their beauty lies a fragility that demands care. Because opals hold water within their very structure, they respond to the world around them—expanding, contracting, and even “thirsting” for moisture.
At Trademark Antiques, we’ve spent almost two decades handling antique and vintage opal jewelry—pieces that glow with a history all their own. In this guide, you’ll learn how to care for opal jewelry so its inner fire continues to shimmer for generations.
Opals are formed from silica and water, holding between 3–21% water in their structure. This gives them their mesmerizing “play-of-color” but also makes them more sensitive to heat, dryness, and sudden temperature changes.
With a Mohs hardness of 5.5–6.5, opals are softer than many gemstones. Antique opals, often set in delicate 19th- or early 20th-century mounts, need extra care to protect both stone and setting.

Opals thrive on gentle wear. Avoid exposing them to chemicals, water, or impact—remove your jewelry before swimming, showering, or exercising. Apply lotions, perfumes, and hairspray before putting on your opal pieces to prevent dulling their natural luster.
Think of your opal like a fine silk scarf or antique book—meant to be loved, but never rushed.

Opals require a light touch when cleaned.
Step-by-step cleaning guide:
Prepare a bowl of lukewarm water with a drop of mild soap.
Gently wipe your opal with a soft cloth or brush.
Rinse in clean lukewarm water and pat dry with a lint-free cloth.
Allow to air dry fully before storing.
Avoid: ultrasonic cleaners, steamers, alcohol, or abrasives. These can permanently damage the gem or loosen antique prongs.
At Trademark Antiques, we handle opal cleaning with utmost care, using only gentle techniques that preserve the gem’s natural glow and its historical setting.

Because opals are hydrated gemstones, maintaining ambient humidity is essential. Store them in a soft-lined box or individual pouch, away from harder gems.
In dry environments, add a dampened cotton pad or sponge inside your jewelry box to help prevent dehydration and crazing (fine cracking).

Each opal type has its own care requirements:
Solid opals – Pure opal throughout, most durable.
Doublets – Thin opal bonded to backing; avoid water exposure.
Triplets – Feature a clear protective cap; keep away from heat.
Boulder opals – Naturally backed by ironstone; sturdy and unique.
Ethiopian opals – Hydrophane and highly absorbent; store carefully.
Australian opals – Classic, stable, and common in antique jewelry.
At Trademark Antiques, we identify and describe each opal so you can care for your heirloom with confidence.

Crazing or cracking: Caused by dehydration or rapid temperature change—maintain steady humidity.
Color fading: Keep opals away from direct sunlight and heat sources.
Scratches and chips: Store separately from harder stones.
Cloudiness: Often from residue or moisture absorption—clean gently and allow time to dry.

Antique opals deserve the hands of experts, and our jeweler carefully restores our opal pieces by gently polishing the stones to restore their original luster and brilliance.

Can opals get wet?
Short exposure is fine, but avoid soaking—especially for doublets or triplets.
How often should I clean my opal ring?
Every few months or as needed. Always use gentle, non-abrasive methods.
Can I wear my opal ring every day?
Yes, with care—remove before activities involving water, heat, or chemicals.
Why is my opal cloudy?
Likely residue or temporary moisture absorption. Let it dry or consult a jeweler.
How should I store opals long-term?
Separately in soft pouches, away from light and heat, with slight humidity.
