This is a large cat's eye, so a few honest questions deserve answers up front. It weighs 13.45 carats.

What colour is it?

Bottle green, with a fine band that contrasts well against the body colour.

Is it too big to wear?

At this size it is a statement stone. It suits a wider shank or a claw setting and is most often chosen for an occasion ring rather than daily wear, though its hardness of 8.5 would cope with regular use.

How do I know the band is genuine?

Turn it slowly under one light. A real chatoyant stone shows its band tightening to a line and then opening as you move it. Fine fibre-like structures inside the stone cause that effect.

Has it been treated?

This family is usually left natural. Message us on WhatsApp quoting AG-CE-0007 for what we know of this exact piece; independent lab testing is your choice.

What happens when I order?

We confirm with you, then dispatch. You open the parcel, check the stone and only then pay. Karachi usually gets it in 1 to 2 working days and other cities in 2 to 4, and you have 7 days to return it unused. See the full cat eye range to compare. 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 13.45 Carat. Its price is Rs. 8,100 — roughly Rs. 602 for each carat. Treatment: treatment not tested. Quote reference AG-CE-0007 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.
