Opal is a gem where the careful buyer should ask questions before paying, and the first is about treatment. In the trade, solid opal is mostly sold as mined, but some stones are smoke-treated or sugar-treated to darken them, and doublets and triplets (thin slices glued to a backing) sit alongside solid stones. GemStore sells solid natural opal only.

This one is a 2.3 carat Ethiopian multi fire opal, SKU GS-000705, priced at Rs. 7,500, about Rs. 3,261 per carat. For what we know about this exact stone, message us on WhatsApp and ask directly. Independent lab testing is available if you want written confirmation.

Ethiopian opal is known for its lively play of colour, and the title describes this one as multi fire, meaning several colours may show as you tilt it. Hold it under both daylight and a warm lamp when it arrives, because opal can look quite different between the two.

Care is simple but important. Mohs 5.5 to 6.5 means opal scratches more easily than most gems in a jeweller's tray. Wash it only with lukewarm water and a soft cloth, then store it wrapped separately. See our general gemstone care guide or the full opal range.

This particular stone

This listing is one natural ethiopian opal with a weight of 2.3 Carat. Its price is Rs. 7,500 — roughly Rs. 3,261 for each carat. Origin: Ethiopia. Treatment: treatment not tested. Quote reference GS-000705 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 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.
