This 4.8 carat natural blue sapphire costs Rs. 12,380 in total, which the arithmetic turns into about Rs. 2,579 per carat. That per-carat figure is the number to carry between stones. In sapphire the rate usually climbs with better colour and clearer crystal, so two stones of the same weight can sit far apart in price.

Comparing rates is useful but never the whole story. Here the stone is a blue neelam with a Mohs hardness of 9, so it will take a ring setting without worry. At just under five carats it has real presence on the hand, without being so large that it catches on sleeves.

Setting thoughts

A closed-back silver setting protects the stone from knocks, while a gold mount suits those who plan to wear it for years.

This particular stone

This listing is one natural sapphire, known in Urdu as Neelam, with a weight of 4.8 Carat. Its price is Rs. 12,380 — roughly Rs. 2,579 for each carat. Treatment: treatment not tested. Quote reference GS-000796 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 sapphire 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 sapphire 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 sapphire 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.
