A natural sulemani agate of 15.20 carats, about 16.70 ratti, at Rs. 10,600 – roughly Rs. 697 per carat. It is the largest stone in this category.

What "premium" means on this page

Three measured things, and nothing else.

Size: at just over fifteen carats, around sixteen and a half ratti, it is the biggest in the tray. Brightness: its average lightness is about 141 on a 0-255 scale, the highest of all sixteen, which in the hand means a luminous cream-and-amber stone rather than a deep brooding one. And rate: at Rs. 697 per carat it sits at the lower end of this category's narrow Rs. 695 to Rs. 704 band, so the largest stone here is not carrying a size premium.

What it does not mean: there is no grade, no certificate and no laboratory opinion of any kind behind this listing, because no laboratory has seen the stone. Banded agate is graded in the trade by how strong and well-placed its pattern is, and that is a judgement, not a measurement.

A large cabochon

Fifteen carats is a substantial stone, and a substantial dome. It makes a bold gents' ring or a pendant, and it will need a setting made for it rather than a ready-made mount. Its banding varies by about 46 units of lightness and about 89% of the face reads as a warm colour, with a broad pale cream zone through the middle. It is not black and white; nothing in this category is.

Hardness

Agate is chalcedony at Mohs 6.5 to 7, with no cleavage planes. Hard enough for daily wear and tough against knocks, which is why agate has been a working ring stone for thousands of years. Its polish softens slowly over years and is easily restored.

What has not been tested

No laboratory report, and the treatment has not been tested. Sulemani agate is sometimes dyed to sharpen its banding. We do not claim this stone is untreated and will arrange an independent test on request.

Care and ordering

Warm water, mild soap and a soft cloth. Avoid ultrasonic cleaners, steam and bleach. One stone, sold once. Message us on WhatsApp for more photographs, and we deliver across Pakistan.

This particular stone

This listing is one natural sulemani agate with a weight of 15.2 Carat. Its price is Rs. 10,600 — roughly Rs. 697 for each carat. Treatment: treatment not tested. Quote reference GS-SU-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 sulemani agate rates 6.5 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy sulemani agate 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 sulemani agate 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.
