A neelam that weighs 24.35 carats and costs Rs. 18,750 brings the rate down to about Rs. 770 per carat, which is low for a neelam, and a good reason to look closely. A low rate on a big stone is often down to colour or clarity, so view photographs in daylight and ask questions.

The stone is a natural blue sapphire with Mohs hardness 9. It is large, so a pendant or a statement ring is the likely home for it. Reference: GS-000778.

Reading a per-carat rate

Per-carat pricing is useful, but it never tells the whole story. Two sapphires with the same weight can differ widely in price because of colour saturation, transparency and how well the stone is cut. That is why we inspect every stone and show it as it is, so you see it before deciding.

This particular stone

This listing is one natural sapphire, known in Urdu as Neelam, with a weight of 24.35 Carat. Its price is Rs. 18,750 — roughly Rs. 770 for each carat. Treatment: treatment not tested. Quote reference GS-000778 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
