Opals are one of the most mesmerising gemstones, known for their vibrant play of colour and unique beauty. As the birthstone for October, they hold a special significance for many. However, unlike harder stones such as diamonds or sapphires, opals require special care to maintain their brilliance and longevity. Whether you own a solid opal, opal doublet, or opal triplet, proper maintenance ensures that your jewellery remains stunning for years to come.
In this guide, we’ll explore everything you need to know about how to care for opals, including cleaning techniques, storage tips, and essential precautions to protect your gemstone from damage.
What Makes Opals Unique?
Opals are composed of hydrated silica, a mineral that contains water molecules within its structure, making up between 6-10% of their composition. This unique structure makes them more delicate than other gemstones, as they are susceptible to drying out, cracking, or losing their vibrancy if not handled correctly.
Types of Opals
- Solid Opals: A single piece of natural opal, the most durable and valuable type. Australian solid opal types include black opal, crystal, boulder and milky (white) opal.
- Opal Doublets: A thin layer of opal attached to a black backing to enhance colour.
- Opal Triplets: Similar to doublets but with an added clear quartz or glass cap for protection.
Due to their unique composition, opals should be treated with extra care to preserve their appearance and structural integrity.
How to Clean Opal Jewellery Safely
Cleaning Solid Opals
Solid opals are relatively easy to clean, provided you use gentle methods:
- Fill a bowl with warm water and add a small amount of mild soap.
- Use a soft cloth or a soft-bristled toothbrush to gently clean the surface.
- Rinse under lukewarm running water and pat dry with a soft, lint-free cloth.
- Avoid harsh chemicals, bleach, or ultrasonic cleaners, as they can damage the stone.
Cleaning Opal Doublets & Triplets
Because doublets and triplets have adhesive layers, they require a different approach:
- Do not soak them in water, as prolonged exposure can weaken the glue.
- Instead, use a damp cloth with mild soap to gently wipe the surface.
- Never use ultrasonic or steam cleaners, as the heat and moisture can cause the layers to separate.
The Best Way to Store Opals
General Storage Tips
- Store opal jewellery in a soft pouch or lined jewellery box to prevent scratches.
- Keep opals separate from harder gemstones like diamonds and sapphires.
- Avoid storing opals in direct sunlight or near heat sources.
Long-Term Storage for Solid Opals
Because opals contain water, they can become brittle if exposed to dry environments for extended periods:
- Store them in a humid environment to prevent dehydration.
- Place a piece of cotton wool dampened with water inside a sealed plastic bag alongside your opals to maintain moisture levels. Check and refresh the cotton wool periodically to prevent mould.
Long-Term Storage for Doublets & Triplets
- Unlike solid opals, doublets and triplets should be kept dry.
- Store them in a cool, stable environment away from humidity or excessive temperature changes.
How to Protect Opals from Damage
- Avoid Hard Knocks: Opals rank 5.5-6.5 on the Mohs hardness scale, making them softer than many other gemstones. Avoid wearing opal rings during activities that could expose them to impact, such as gardening or sports.
- Protect from Extreme Temperatures: Rapid changes in temperature can cause cracks or crazing in opals. Never expose them to extreme heat or freezing conditions.
- Keep Away from Chemicals: Household cleaners, hairspray, perfume, and cosmetics can dull opals over time. Remove your jewellery before using these products.
Wearing Opals: Daily Care Tips
Wearing opals regularly can help maintain their natural moisture levels, but proper precautions are necessary to prevent damage:
- Remove opal rings before sleeping to avoid accidental knocks.
- Check for signs of dullness, cloudiness, or cracks regularly.
- If your opal loses its shine, a professional polishing service can restore its lustre.
Professional Care for Opals
If your opal jewellery becomes scratched or appears lacklustre, take it to a professional jeweller for maintenance:
- Repolishing: Professional polishing can restore opals to their original shine.
- Checking Settings: Loose prongs or settings can cause opals to fall out—have them inspected periodically.
- Repairing Doublets & Triplets: If water damage occurs, a jeweller may be able to reattach the layers.
Frequently Asked Questions (FAQs)
Can opals get wet?
Solid opals can be exposed to water without harm, but doublets and triplets should be kept dry to prevent delamination.
How do I know if my opal is solid or a doublet/triplet?
Examine the side of the stone—if you see a clear division between layers, it’s likely a doublet or triplet. Solid opals have a consistent texture throughout.
What should I do if my opal loses its shine?
Try gently cleaning it with mild soapy water. If the dullness persists, seek professional polishing.
Are opals fragile?
While opals are softer than some gemstones, they are durable with proper care. Choosing protective settings for rings can also reduce the risk of damage.
Can I wear my opal ring every day?
Yes, but consider using a protective setting, such as a bezel, to safeguard against knocks and scratches.
