"Premium quality" is the least useful phrase in the gemstone trade, because nobody has to define it. With opal it can at least be made concrete, because opal has one dominant value driver and it is visible to anyone: how brightly the colour fires.

The stone

2.20 carats, which is 2.42 ratti. Shape: oval cabochon. Origin: Australia. Rs. 11,000, about Rs. 5,000 per carat, reference GS-000704.

Look at that rate against the Rs. 768 per carat stone in the same collection — an eleven-fold difference in the same gem from the same country, at a similar size. That gap is the claim this page has to justify.

What separates a premium opal from an ordinary one

1. Brightness. The single biggest factor by a wide margin. A premium stone announces its colour at arm's length in ordinary room light. An ordinary one needs daylight and a tilt to find.
2. Coverage. Colour across the whole face, not a bright corner with dead ground around it. Dead ground is where cheap opal hides.
3. Which colours fire. Red is the scarcest and most valuable, then orange, then green, then blue. A stone that produces red at all is in a different bracket.
4. Range of angles. Tilt it slowly. Premium material keeps producing colour through a wide arc; weaker stone flashes once and dies.
5. Pattern. Broad, defined flashes beat fine scattered pinfire for value, though pinfire has its own admirers.
6. A clean dome. Smooth and even, with no flat spot or sand pocket on the surface.

What we have not verified

Being straight about this is part of the same argument. Measurements and a formal body-tone or brightness grade are not recorded for this stone — those fields stay blank rather than being filled with plausible-sounding values. Treatment has not been tested either: solid opal is usually untreated, but some material is smoke- or sugar-treated to darken the background, and we will not claim a stone is untreated without a report. Ask us on WhatsApp at +92 308 887 3888 and we will measure it, send a video under moving light, or arrange independent laboratory testing.

Is it worth paying eleven times more per carat?

Only if you can see it. Open this listing and our cheapest opal side by side in two browser tabs and compare the photographs at full size — nothing on this site is colour-corrected. If the difference is not obvious to you, buy the cheaper stone. We would rather sell you the right one than the dearer one.

Does premium mean certified?

No — separate claims. A certificate of authenticity is available on request and independent testing can be arranged, but no certificate grades beauty, and with opal beauty is almost the whole price.

Solid opal

We sell solid natural opal, not doublets or triplets. Check any opal edge-on for the straight glue line where layers are joined. See our real versus fake opal guide.

Care

Opal is 5.5 to 6.5 on the Mohs scale and holds water. Soft damp cloth only, never ultrasonic or steam, and keep it out of prolonged sun and dry heat. A bezel setting protects the edge better than claws.

Ordering

One piece only. Flat Rs. 500 delivery anywhere in Pakistan, insured and tracked, dispatched in one to two working days. Cash on Delivery, seven days to return it unused. Compare the range in the Australian opal collection.

This particular stone

This listing is one natural australian opal with a weight of 2.2 Carat. Its price is Rs. 11,000 — roughly Rs. 5,000 for each carat. Origin: Australia. Treatment: treatment not tested. Quote reference GS-000704 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.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

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, a certificate is available on request, 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. Certificate available on request. 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.
