At 7.2 carats and Rs. 12,380, this Madagascar ruby comes to about Rs. 1,719 per carat. In ruby the per-carat rate is the figure to watch, because it climbs steeply with colour depth and transparency; two stones of equal weight can sit at very different totals. Over seven carats is a substantial ruby, so the rate tells you more than the headline price does.

Treatment and testing

Ruby is very often heated, and low-grade material may carry glass filling, which is not something we would call natural ruby. We will tell you what we know about this exact piece, and independent lab testing is available on request.

For a setting, remember that hardness of 9 protects against scratches but not against a sharp knock. A bezel or well-guarded claws suit a ring; a pendant is gentler still. Our introduction to rubies covers colour and sources in more depth, and more weights wait in the ruby category.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 7.2 Carat. Its price is Rs. 12,380 — roughly Rs. 1,719 for each carat. Origin: Madagascar. Treatment: treatment not tested. Quote reference GS-000557 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, 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.
