Mid-sized rubies bring up the same questions again and again, so here are plain answers for this 7.15 carat red yaqoot, reference AG-000555.

Is it a good size?

Seven-plus carats is a generous weight for ruby, substantial on a ring finger without being unwieldy, and it is gently priced for that weight.

Has it been heated?

The listing alone cannot tell you. Heating is routine across the ruby trade, and glass-filled stones exist at the lower end; we never sell those as natural ruby. Ask on WhatsApp and we will pass on whatever we know about this particular stone.

Is it hard enough for a ring?

Yes. Ruby is 9 on the Mohs scale, so daily knocks and household dust will not scratch it. A hard blow can still chip the edge of any gem, so a setting that protects the girdle is wise.

Can I see it before paying?

Yes. You open the parcel and inspect the stone first. Our ruby collection has other weights to compare, and the guide to ruby quality explains what to look for in colour and transparency.

When it arrives, open it with the rider still there and pay only if you are happy. Karachi usually gets it in 1–2 working days, the rest of Pakistan in 2–4, and you can return it within 7 days in its original packing.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 7.15 Carat. Its price is Rs. 12,750 — roughly Rs. 1,783 for each carat. Treatment: treatment not tested. Quote reference AG-000555 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.
