In Pakistan, opal is often bought for its association with Venus in Vedic astrology and for its shifting colours, and black opals attract particular interest because the dark body makes the colour stand out. As tradition goes, opal is worn on the advice of a trusted astrologer, and no result is promised by us.

Now the hard facts about this stone. It is a natural black Ethiopian opal weighing 4.35 carats, SKU GS-000722. The price is Rs. 13,050, which is exactly about Rs. 3,000 per carat. Rely on the photographs and ask for more if you need them.

Wear and care are simple to state. Hardness is 5.5 to 6.5 on the Mohs scale, so keep it from hard knocks, heat and strong chemicals. A pendant is gentler on it than a ring.

Finally, treatment. Solid opal is usually sold as it comes, although smoke and sugar treatments exist and doublets and triplets can be found. We offer solid natural opal, and you may ask on WhatsApp for what we know about this particular stone. Independent lab testing is available on request. More are in the opal collection.

This particular stone

This listing is one natural ethiopian opal with a weight of 4.35 Carat. Its price is Rs. 13,050 — roughly Rs. 3,000 for each carat. Origin: Ethiopia. Treatment: treatment not tested. Quote reference GS-000722 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.
