A 7.70 carat ruby at a modest rate for its weight deserves careful questions, and we would rather you asked them than assumed. Heating is routine in the ruby trade, and lower-grade stones are sometimes glass-filled to disguise fractures. We would never sell such a stone as natural ruby, but a careful buyer should question any ruby, particularly one priced modestly.

A lower rate is not a defect in itself. Colour depth, transparency and clarity all move a ruby's value. Message us on WhatsApp quoting AG-000556 and we will tell you what we know about this exact piece, including what is known of its heating.

What we can state plainly: it is red, it is a natural ruby, and it measures 9 on the Mohs scale. If you want certainty beyond that, independent lab testing is your option.

Compare it with the other ruby listings, or read how we think about authenticity. With Cash on Delivery you hold the stone in daylight before you pay anything.

No advance payment is needed. We dispatch on Cash on Delivery, you inspect before paying, Karachi addresses usually receive it in 1–2 working days and other cities in 2–4, and a 7-day return is there as a safety net. Read our ruby guide first.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 7.7 Carat. Its price is Rs. 6,380 — roughly Rs. 829 for each carat. Treatment: treatment not tested. Quote reference AG-000556 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.
