Heat treatment is routine in the ruby trade, and a careful buyer should ask about it before paying for any stone. Ruby is often heated to improve colour, and the lowest grades may also be glass-filled. We do not sell glass-filled ruby as natural ruby, but only a conversation about the specific piece will settle where it stands.

For this 2 carat ruby from Africa, the honest position is that treatment is common in the family and we can tell you what we know about this particular stone. Message us on WhatsApp with the reference GS-000526, and if you want independent confirmation, a lab test can be arranged on request.

What we can state about the stone

It is red, weighs 2 carats and comes from Africa. The price is Rs. 9,750, which is about Rs. 4,875 per carat. Hardness is 9 on the Mohs scale, tough enough for a ring that is worn regularly with ordinary care.

A small stone like this sits comfortably in a simple silver mounting, and the seven-day return window after delivery means you can look at it properly in daylight before settling on a design. The wider range is under ruby (yaqoot), and our authenticity page explains how we handle disclosure.

Pay Cash on Delivery once you have opened the parcel and seen the stone yourself, anywhere in Pakistan, with 7 days to return it if you change your mind. Before you choose, read our ruby guide.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 2 Carat. Its price is Rs. 9,750 — roughly Rs. 4,875 for each carat. Origin: Africa. Treatment: treatment not tested. Quote reference GS-000526 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.

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, 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.

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.
