4.75 carats — 5.22 ratti — at Rs. 1,800, about Rs. 379 per carat. The reference is GS-MO-0008.

What the photograph actually shows

Needle coverage reads 50% — exactly half the face — but the open quartz measures only 7%, the lowest in the collection. The difference between those two figures is the interesting part: where most stones here are either needle or clear window, this one has a good deal of greyish, slightly milky quartz between the needles rather than fully open crystal.

The material is tourmalinated quartz: colourless rock crystal with black tourmaline needles inside it. Here the quartz between the needles is cloudier than usual rather than fully open.

In practice that gives it a softer, cloudier look than its neighbours — less contrast, more of an even smoky grey. Some people prefer that to the stark black-on-clear of the more transparent stones; it is a quieter stone.

The polish

Quartz takes an excellent polish, and this one has it: the face is flat, even and bright, with no dulling at the edges where a hurried finish usually shows first. That matters more on an included stone than on a clear one, because a poor polish scatters light at the surface and makes the inclusions harder to read.

At 7 on the Mohs scale, the polish will also last — this is not a stone you will be sending back for refinishing.

Wearing it

Just under 5 carats suits a ring or a small pendant. Quartz is genuinely practical for daily wear, which is not true of most of the opaque stones in our range.

Care

Warm soapy water and a soft brush. No ultrasonic cleaner, and avoid sudden temperature changes, which can stress the boundaries between needle and host.

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.

This particular stone

This listing is one natural moh-e-najaf with a weight of 4.75 Carat. Its price is Rs. 1,800 — roughly Rs. 379 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0008 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.
