Five carats and Rs. 8,250 give a rate of about Rs. 1,650 per carat for this ruby. For a stone of this weight, that is among the gentler rates in our range, and it deserves a careful look at the colour and clarity before any decision.

Colour and hardness

The stone is red and rates 9 on the Mohs scale. A five-carat ruby is a heavy stone, and it carries best in a ring with a broad base or in a pendant.

Heat is common in ruby, and weaker grades may be glass-filled. We keep glass-filled stones out of our natural ruby listings. To find out what we know about this stone, message us on WhatsApp with the reference GS-000547.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 5 Carat. Its price is Rs. 8,250 — roughly Rs. 1,650 for each carat. Treatment: treatment not tested. Quote reference GS-000547 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.
