3.60 carats — 3.96 ratti — at Rs. 1,350, about Rs. 375 per carat. The reference is GS-MO-0002.

The cut

A true oval — a continuously curved outline with no flattened sides or squared corners, standing a little taller than it is wide. Several stones in this collection are cushions, rounded squares with four distinct corners, and we have not called any of those oval.

The practical consequence is that this one drops into a standard oval bezel or setting without custom work, which is worth real money if you are having something made.

What the photograph shows

Needle coverage reads 40% and brightness 101 out of 255, which places it in the lighter, more open half of this collection. The needles are moderately dense and run in long straight lines across the face rather than matting together, so the pattern stays readable.

What Moh-e-Najaf is

In Pakistan the name covers quartz from the Najaf tradition, and it is applied both to plain colourless rock crystal and — as here — to quartz carrying black tourmaline needles inside it. Both are quartz; the difference is what grew inside the crystal before it closed.

The needles are schorl, the black iron tourmaline. They formed first, and the quartz grew around them.

Wearing it

At 3.60 carats this is a modest everyday ring stone or a neat pendant. Quartz at 7 on the Mohs scale takes daily wear comfortably.

Care

Warm soapy water and a soft brush. No ultrasonic cleaner, and avoid sudden temperature changes.

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. Message +92 308 887 3888 for exact dimensions. The rest of the range is in the Moh-e-Najaf 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 moh-e-najaf with a weight of 3.6 Carat. Its price is Rs. 1,350 — roughly Rs. 375 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0002 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.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

On the Mohs scale moh-e-najaf rates 7. It handles daily wear, but a hard knock can still nick an exposed corner, so a protective setting is a sensible choice. Clean it with warm soapy water and a soft brush, and keep it away from abrasive cleaners and high heat.

Whoever you buy moh-e-najaf 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 moh-e-najaf 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.
