A 20.1 carat natural blue sapphire suits someone who wants a statement piece without paying for a very high per-carat rate. It is listed at Rs. 18,750, about Rs. 933 per carat, and that gentle rate is typical for large sapphires, which are generally priced lower per carat than small ones of comparable quality.

How you might wear it

Twenty carats calls for a broad, secure setting: a cocktail-style ring, a large pendant, or a bespoke piece. Sapphire sits at 9 on the Mohs scale, so the stone itself will cope with wear. Custom silver ring settings can be discussed with us on WhatsApp.

This particular stone

This listing is one natural sapphire, known in Urdu as Neelam, with a weight of 20.1 Carat. Its price is Rs. 18,750 — roughly Rs. 933 for each carat. Treatment: treatment not tested. Quote reference GS-000803 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.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

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.
