A natural red agate of 7 carats, about 7.69 ratti, at Rs. 4,900 – exactly Rs. 700 per carat. It is an oval cabochon, cut noticeably wider than it is tall: measured from the photograph its outline is about 1.43 times as wide as it is deep, where a circle would measure 1.00.

What a cabochon is, and what it is not

A cabochon is shaped and polished into a smooth dome with no facets at all. It is the oldest way of finishing a gemstone and still the right one for material like agate, which is not transparent enough for faceting to do anything useful. Facets work by bouncing light back out of a clear stone; in a dense, opaque body they simply break up the surface. A dome instead gives you an unbroken sweep of colour and a single soft highlight, which is what you see on this one.

"Oval cut" is the trade's way of describing the outline rather than the finish. Taken together: oval outline, domed top, flat or gently curved base that sits down in a setting.

The colour

This is one of the more strongly coloured stones here. Measured across the face, about 96% of its surface reads as a saturated red, the highest proportion in the tray, and it is noticeably more open than the near-black agates at the small end. Expect a clear, warm red rather than a closed claret.

Hardness

Agate is chalcedony at Mohs 6.5 to 7, with no cleavage planes. That makes it tough against impact and a sensible choice for a ring worn daily. Fine abrasion from household dust will soften a cabochon's polish over years; a jeweller restores it quickly.

What is not established

No laboratory report exists for this stone, and its treatment has not been tested. Red agate is often heated or dyed to deepen or even out its colour. We do not claim this one is untreated. No origin is recorded for it, so none is stated.

Care and ordering

Warm water, mild soap and a soft cloth are enough. 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 red agate with a weight of 7 Carat. Its price is Rs. 4,900 — roughly Rs. 700 for each carat. Treatment: treatment not tested. Quote reference GS-RE-0006 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 red 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 red 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 red 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
