This purple sapphire listing does not carry a carat weight, so please confirm the figures with us before you decide. Send reference AG-000508 on WhatsApp and we will give you the details for this exact stone.

What the stone is: a natural purple sapphire, sold in Pakistan as a kind of neelam, rated 9 on the Mohs scale. That hardness makes it practical for rings, because it resists scratches from daily wear far better than amethyst, which it can resemble in colour but not in toughness.

On treatment, purple sapphire tends to be heated for colour, and untouched stones are the exception, so a buyer should ask rather than assume. We will tell you what we know about this piece, and independent lab testing is your option if you want it.

If you are comparing, the purple sapphire category lists other stones with their weights, so you can see where this one sits once you have its figures.

This particular stone

This listing is one natural purple sapphire with a weight of 11.35 Carat. Its price is Rs. 4,240 — roughly Rs. 374 for each carat. Treatment: treatment not tested. Quote reference AG-000508 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 purple 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 purple 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 purple sapphire for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
