Who buys a 13.30 carat jet-black cat's eye? Usually someone after an occasion ring that people notice, or a pendant with a bold, simple look. It is a statement, not a delicate stone, and the pale band across a black body stops it looking flat.

The stone

It is natural cat's eye chrysoberyl, 13.30 carats, jet black with a fine band that contrasts sharply against the body. Chrysoberyl scores 8.5 on the Mohs scale, more than tough enough to wear.

Setting and checking

A stone this size does best in a wide shank or a claw setting. If you would like a custom silver ring, message us on WhatsApp quoting AG-CE-0016 and we can discuss it.

When the parcel arrives, hold the stone under one light and turn it: the band should tighten to a line and then open. Lehsunia is not normally enhanced, and we will pass on what we know about this piece if you ask. Independent lab testing is your choice.

See the cat eye stones for similar pieces.

Keep it in a pouch of its own and wipe it after wearing.

Cash on Delivery lets you open the parcel and inspect the stone before you pay. Karachi usually receives orders in 1 to 2 working days and the rest of Pakistan in 2 to 4, with 7 days to return it unused. Before you choose, read our cat eye guide.

This particular stone

This listing is one natural cat eye, known in Urdu as Lehsunia, with a weight of 13.3 Carat. Its price is Rs. 9,980 — roughly Rs. 750 for each carat. Treatment: treatment not tested. Quote reference AG-CE-0016 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 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.
