5.69 carats — 6.25 ratti — at Rs. 2,180, about Rs. 383 per carat. The reference is GS-MO-0011.

What makes it the pick of the larger stones

Two things, both measurable. Needle coverage reads 54% — close to the middle of this collection's 28% to 62% range, which is the balance most people want: enough tourmaline to make the pattern the feature, enough open quartz to keep it from going solid black. And brightness measures 82 out of 255, so the stone still carries light rather than reading as a dark mass.

The needles themselves are long and cleanly separated rather than matted together, which is what gives the face its structure.

What "premium" means here

It means the best balance of needle pattern and open crystal among the stones on this page, judged against the other twelve. It does not mean a laboratory has graded it — nothing in this category has been tested, and we are not going to imply otherwise.

What the material is

Colourless quartz with black tourmaline needles grown inside it. The trade calls it tourmalinated quartz; in Pakistan it is sold under the Moh-e-Najaf name alongside plainer clear quartz. Both are quartz. The difference is what is suspended inside.

Wearing it

Nearly 6 carats is a practical ring size, and quartz at 7 on the Mohs scale is one of the more sensible choices for a stone worn every day. Use a bezel: the needles create planes of weakness, so the edges want protecting even though the material itself is hard.

Care

Warm soapy water and a soft brush are safe. No ultrasonic cleaner, and avoid sudden heat.

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 with the reference. 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 5.69 Carat. Its price is Rs. 2,180 — roughly Rs. 383 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0011 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.
