Who is a 5.7 carat ruby for? Anyone who wants a good amount of red stone at a rate well below the usual ruby levels. This one is Rs. 9,000 in total, about Rs. 1,579 per carat, and the reason to ask questions is the same reason it appeals: at this rate, you should know exactly what you are buying.

Questions worth asking

Ruby is often heated, and lower grades may be glass-filled. We keep glass-filled ruby out of the natural category entirely. Write to us on WhatsApp with reference GS-000514 and we will tell you what we know about this stone; independent lab testing is available if you want a report before you decide. Cash on Delivery means you can inspect the stone before paying.

Living with it

It is red, natural, and rated 9 on the Mohs scale, so a pendant, a ring or a pair of earrings would all cope. At 5.7 carats it is a presentable size for a ring, so protect the edges with a sturdy setting. Wipe it clean with warm water and mild soap, and avoid steamers and ultrasonic cleaners if the stone has had any fracture filling.

Other stones are in our ruby category.

This particular stone

This listing is one natural ruby, known in Urdu as Yaqoot, with a weight of 5.7 Carat. Its price is Rs. 9,000 — roughly Rs. 1,579 for each carat. Treatment: treatment not tested. Quote reference GS-000514 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.
