10.99 carats — 12.08 ratti — at Rs. 6,600, about Rs. 601 per carat. The reference is GS-JD-0017.

The darkest and the strongest colour in the collection

We measured every photograph in this collection the same way, and this stone takes both ends of the scale. Its brightness reads 85 out of 255, the lowest of all of them, and its saturation measures 90%, the highest. Nothing else here is as deep or as intensely coloured.

That is an unusual combination. Most stones lose saturation as they darken, because there is less light coming back to carry the colour. This one holds a rich, bottle-green depth that reads almost black in poor light and opens up properly when you take it to a window.

Its lightness varies across the face by 40 points, so there is real movement in the body — denser passages and lighter ones rather than one flat tone.

The cut

It is the most upright stone in the collection, measuring 0.68 across its outline — noticeably taller than it is wide. That gives it height on the hand and a different presence from the flat rectangles elsewhere on this page. It will want a setting made for its proportions rather than a stock oval bezel.

Wearing it

Eleven carats of deep green with that upright profile is a statement ring, or a pendant with real weight to it. Dark stones look best against cool metal — silver, white gold, or an oxidised finish, where the contrast lifts the colour.

Care

Warm water and a soft cloth. No ultrasonic cleaner, no hot water, and keep it away from bleach and household cleaners. Deep green stones are more often colour-treated than pale ones, and strong chemicals can affect a treated surface.

We have not had this stone tested, so its treatment is recorded as "not tested" rather than untreated, and we hold no documented origin for it. Independent testing can be arranged on request — message +92 308 887 3888 with the reference. The rest of the collection is in the jade category.

Cash on Delivery is available across Pakistan, so you inspect the stone before paying, and returns are accepted within 7 days of delivery.

This particular stone

This listing is one natural jade, known in Urdu as Yashab, with a weight of 10.99 Carat. Its price is Rs. 6,600 — roughly Rs. 601 for each carat. Treatment: treatment not tested. Quote reference GS-JD-0017 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 jade rates 6 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 jade 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 jade 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. As general background (not a statement about this stone): Jade (yashab) may be dyed or polymer-impregnated; untreated jade costs more. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.
