At 11.3 carats this opal gives you room to design, and silver is the natural partner for the flashing colours of Australian fire opal. A wide bezel pendant, a statement ring for occasions or a pair of bold earrings all suit this weight.

Opal is on the soft side, 5.5 to 6.5 on the Mohs scale, so a pendant is the safest choice, and a ring is best with a rim that stands above the stone. If you want a custom silver ring setting, we can talk it through on WhatsApp.

About this stone

It weighs 11.3 carats and comes from Australia. Its rate per carat is lower than on our smaller opals, because bigger stones tend to cost less per carat; what really matters is how bright and widespread the colour flashes are. Trust the photos rather than any single number.

Opal is not commonly enhanced, though you should still ask; quote AG-0009 and we will tell you what we know. Some traditions treat opal as a stone of creativity, which we pass on as belief only. More are in the opal section.

Cash on Delivery lets you inspect it before paying; Karachi usually gets it in 1–2 working days, other cities in 2–4, and returns are open for 7 days. Read our gemstone buying guide.

This particular stone

This listing is one natural australian opal with a weight of 11.3 Carat. Its price is Rs. 29,630 — roughly Rs. 2,622 for each carat. Origin: Australia. Treatment: treatment not tested. Quote reference AG-0009 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

Whoever you buy australian opal from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone. We check every australian opal for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome. As general background (not a statement about this stone): Solid opal is usually untreated; some opal is smoke- or sugar-treated, and doublets/triplets exist — we sell solid natural opal. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
