Silver works beautifully with a dark stone, and this 2.25 carat black fire opal would look tidy in a silver pendant or workable in a slim ring. If you want a custom silver ring setting, we can discuss it on WhatsApp; quote the reference AG-000726.

It is a natural stone, listed as black fire opal. Ask us for photographs from other angles if you want more detail. For opal, a per-carat rate only gives you a sense of the market; the colour display decides the rest, so a short video is worth requesting.

Setting and wear

Opal is only 5.5 to 6.5 on the Mohs scale, so choose a setting that protects the edges, ideally a bezel. Keep it away from heat and strong chemicals, and store it apart from harder gems.

As always with opal, treatment is the question to raise. Solid opal is usually left as it is, but smoke or sugar treatment exists, and doublets and triplets circulate. We sell solid natural opal and will tell you what we know about this one. Independent testing is up to you.

You pay only after opening the box and checking the stone. Karachi deliveries usually take 1–2 working days, the rest of Pakistan 2–4, with 7 days to return.

This particular stone

This listing is one natural opal with a weight of 2.25 Carat. Its price is Rs. 7,500 — roughly Rs. 3,333 for each carat. Treatment: treatment not tested. Quote reference AG-000726 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.

On the Mohs scale opal rates 5.5 to 6.5. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy 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 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.
