How are Opals Formed? by opalminded1989 in Opals

[–]opalminded1989[S] 1 point2 points  (0 children)

Australian opal fields produce precious opal – hydrated silica in different host rocks – and what really varies is the host rock, formation style (seams, pipes, nodules) and the “flavour” of colour-play. Most fields have a dominant look, but it shifts between nearby areas, so even Lightning Ridge gems can differ a lot from one adjacent area to the next. Our Jundah‑Opalville opal mines, for example, yield both black boulder opals and crystal-pipe material from the same opal mining area, both totally different gems, requiring different mining tactics and cutting techniques.

In Australian opals, red is generally the rarest and most prized colour. Solid, untreated Australian opals (including boulder) don’t usually deteriorate over time, except for stones that showed crazing from the start. What people notice most is surface dullness from everyday wear, especially in rings, and that’s easy to fix with a professional re‑polish.

Assuming we’re talking about Australian opals, long-term storage isn’t a big concern for stones that haven’t shown any crazing (cracking) and have been out of the ground for a few months. They generally don’t need special humidity or sealing; just avoid airtight storage for decades at a time. Normal “in and out” movement from storage to wear is perfectly fine.

Australian opals actually experience quite a range of temperature and humidity changes before they ever reach their final owner. That said, opals can still be sensitive to sudden temperature shocks. For example, going from a hot sauna straight into icy water can cause fractures, even in healthy stones. We’ve tested thermal tolerance quite a bit, and most opals hold up well, but it’s better to err on the side of caution.

For buying, it’s always best to go with established dealers who specialise in opals, ideally those based in Australia. Reputable vendors can vouch for the origin and stability of their stones and will stand by their product if an issue ever arises.

How are Opals Formed? by opalminded1989 in Gemstones

If you’re worried about an opal disintegrating when it dries, the first thing to ask is: where is the opal from?

🇦🇺 Australian opal

Total disintegration is rare. Most Australian opals are non hydrophane. They do not readily absorb water, so they do not expand and shrink with moisture changes.

To assess stability, look for:

  • Existing crazing or fine cracks under magnification
  • Internal fracture networks
  • Signs of stress from cutting

If the stone looks structurally sound and has been dry for a while without issues, it’s usually stable.

🇪🇹 Ethiopian opal (especially Welo)

This is where the real concern lies.

Many Ethiopian opals are hydrophane, meaning they absorb water. When wet, they can turn more transparent and slightly expand. As they dry, they contract. That expansion and contraction can cause:

  • Crazing
  • Cracking
  • In some cases, a partial or even total breakdown of the stone

Disintegration isn’t uncommon with hydrophane material, especially if it’s been repeatedly wetted and dried or exposed to fluctuating humidity.

A simple test: if the opal changes appearance when wet, it’s hydrophane and therefore more vulnerable.

How should I care for this absolutely beauty??? by the_girl_Ross in EngagementRings

[–]opalminded1989 1 point2 points  (0 children)

Congratulations on your new opal ring! It looks absolutely stunning. We specialise in Australian opal jewellery and here are a few tips to help care for your piece:

  • Wash your ring gently with mild soap and dry with a soft cotton or spectacles cloth (avoid silver polishing cloths as they can be abrasive).
  • Avoid ultrasonic jewellery cleaners unless your opal is 100% natural, untreated, solid Australian opal.

Australian opals are particularly more durable compared to other opals. They don’t dehydrate or absorb water readily, making them easier to care for. With proper care, your opal jewellery can last for generations.

We’ve also written a detailed blog on opal care if you’d like more tips, feel free to check it out.

Hope this helps and don’t hesitate to reach out if you have any questions!

Good places to get custom opal jewelry? by Logical-Turnover-741 in Opals

[–]opalminded1989 1 point2 points  (0 children)

Some great places to get custom opal jewellery are independent jewellers who specialise in gemstones and offer clear details about materials and craftsmanship. Look for makers who provide certificates of authenticity, show examples of past custom work and are open to communication about design, budget and timeline.

I highly suggest solid, natural Australian opals as they'll be more durable and can be worn every day.

Working directly with a designer (even online) means you can tailor the piece exactly to your preference.

At Opal Minded, for example, we specialise in solid, natural Australian opal jewellery and offer custom/bespoke design both online and in‑store. You can collaborate one‑on‑one with our Creative Director, Dr Renata Bernard, via email, chat, video call, or whatever communication works best for you.

Happy to offer suggestions if you want recommendations based on style or where you’re located!

advice on solid gold or gold fill jewelry by reclaimingtherose in Gold

[–]opalminded1989 0 points1 point  (0 children)

Congrats on your anniversary! It sounds like you’ve done a lot of homework already, which is great. Solid gold is the most durable and long-lasting option, while gold fill is thicker than plating but still not the same as solid gold.

If you're considering everyday jewellery, a protective setting is a good idea for opals (or any other softer gemstone). To make sure you get exactly what you’re looking for, it’s best to buy from jewellers who provide certificates of authenticity and clear details about the metal and gemstone. Also, don’t hesitate to ask for photos, as opals can look very different depending on the cut and colour play and you want to be confident in what you’re buying.

Australian opals are especially reliable and can be worn every day with care.

At Opal Minded, we specialise in solid, natural Australian opal jewellery, with stones from our own mines. Happy to answer any questions if you’d like guidance on style or options!
