At 10.40 carats this is a ruby for someone who wants a visible yaqoot on the hand or at the neck, not a quiet accent. For this much weight, the price is one many buyers will find easy to live with.

How a stone this size wears

Ruby rates 9 on the Mohs scale, so everyday scratching is not the concern; a hard knock on an exposed edge is. In a ring, ask for a protective bezel or deep prongs. As a pendant, a heavier stone hangs safely away from desks, doors and kitchen counters. The colour is red and the listed origin is Kashmir. We can discuss a custom silver ring setting on WhatsApp.

Treatment and paperwork

Heating is usual for ruby, so treat it as a question to put to us rather than something to assume. Message us with reference AG-000524 and we will tell you what we know about this stone. Independent lab testing is your choice if you want a report.

In Vedic astrology ruby is linked with the Sun, and many families still consult an astrologer before wearing one. More red stones are in our ruby collection.

You pay only after opening the parcel and seeing the stone with your own eyes. Karachi deliveries normally take 1–2 working days, the rest of the country 2–4, and an unused stone can come back within 7 days. Our ruby guide is worth reading.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 10.4 Carat. Its price is Rs. 23,630 — roughly Rs. 2,272 for each carat. Origin: Kashmir. Treatment: treatment not tested. Quote reference AG-000524 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.

On the Mohs scale ruby rates 9. Few materials will scratch it, so it copes well with everyday ring wear. A soak in warm water with a drop of mild soap and a soft brush keeps it bright; skip the ultrasonic cleaner if inclusions reach the surface.

Whoever you buy ruby 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 ruby 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): Most ruby (yaqoot) is heated, and lower grades may be glass-filled; we do not sell glass-filled ruby as natural ruby. 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.
