4.05 carats — 4.45 ratti — at Rs. 1,540, about Rs. 380 per carat. The reference is GS-MO-0004.

What the photograph shows

Needle coverage reads 46% and brightness 97 out of 255 — a little under half the face in tourmaline, with the rest carrying light. That puts it in the brighter, more open half of this collection without tipping into the near-clear stones at the top of the range.

The needles run mostly in two crossing directions rather than scattered at random, which gives the face a woven look.

Cut as a cabochon

This is an unfaceted stone: shaped and polished with a smooth surface and no cut facets. For an included quartz that is usually the better choice. Facets reflect light back at you from the surface, which competes with the inclusions; an unfaceted face lets you look straight into the stone and see the needles at their real depth.

It also makes the stone easier and cheaper to set, and leaves no facet junctions to chip.

Why it suits a ring

Four carats is a practical everyday size, and quartz at 7 on the Mohs scale is hard enough to take daily wear — harder than steel, and far more durable than the malachite, lapis or jade elsewhere in our range. This is a stone you can genuinely wear without thinking about it.

Use a bezel: the needles create planes of weakness along their length, so although the quartz is hard, the edges are worth protecting.

Care

Warm soapy water and a soft brush — one of the few stones we sell that you can clean properly. 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 to discuss a setting. 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 4.05 Carat. Its price is Rs. 1,540 — roughly Rs. 380 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0004 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. As general background (not a statement about this stone): Moh-e-Najaf (included quartz) is usually untreated. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
