The numbers

This Ethiopian opal weighs 6.1 carats and costs Rs. 13,730, which is about Rs. 2,251 per carat. In opal, the per-carat figure mostly reflects how strong and how broad the play-of-colour is, and how much of the stone shows it. A larger piece at a modest rate gives you a lot of visible surface for the money, but a bigger stone also offers more area to catch a knock.

Ethiopia is one of the better-known modern sources of opal, and its stones are often noted for lively flashes of colour. Your best check is to view it in different lights once it arrives: the colour should move as you turn it, not sit flat in one patch.

On hardness, opal rates 5.5 to 6.5. That makes a pendant or brooch a sensible home for a 6.1 carat piece. A ring is possible, but choose a bezel-style setting that shelters the edges, and ask us about a custom silver ring on WhatsApp.

Smoke or sugar treatment and glued doublets do occur in opal generally; ours are solid natural stones, and we will share what we know about this one, reference GS-000736. See the rest of the opal collection for comparison.

This particular stone

This listing is one natural ethiopian opal with a weight of 6.1 Carat. Its price is Rs. 13,730 — roughly Rs. 2,251 for each carat. Origin: Ethiopia. Treatment: treatment not tested. Quote reference GS-000736 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 ethiopian 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 ethiopian 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.
