A short list for anyone considering this 7.25 carat black cat's eye.

• The body colour is a deep brown-black with a narrow, well-centred band.
• It is natural chrysoberyl, the family behind genuine lehsunia, rated 8.5 on the Mohs scale.
• Check the band first: under one light it should tighten to a line and open again as you rotate the stone.
• Look at the colour in daylight as well as indoors, as brown-black can look warmer outside.
• Treatment is not usual for this family, but ask us what we know of this exact stone.

At 7.25 carats it suits a man's silver ring without needing a heavy mount, and the dark body keeps the band easy to see.

This particular stone

This listing is one natural cat eye, known in Urdu as Lehsunia, with a weight of 7.25 Carat. Its price is Rs. 5,480 — roughly Rs. 756 for each carat. Treatment: treatment not tested. Quote reference AG-CE-0011 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 cat eye rates 8.5. 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 cat eye 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 cat eye 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome.
