3.50 carats — 3.85 ratti — at Rs. 1,310, about Rs. 374 per carat. The reference is GS-MO-0001. It is the smallest and the least expensive stone in this collection, and also one of the clearest.

What Moh-e-Najaf costs, and what moves the price

Most stones on this page sit between Rs. 374 and Rs. 386 per carat, so weight is doing nearly all the work — an 9.55 carat stone costs roughly two and a half times a 3.70 carat one because it is roughly two and a half times the stone.

Two stones break that pattern at around Rs. 450 per carat, and the reason is clarity: they carry fewer inclusions and more open crystal, which is harder to find. So if you see Moh-e-Najaf priced well above the usual rate, look at how much you can see through it before assuming you are being overcharged.

This stone is the interesting case. It is priced at the ordinary rate, Rs. 374 per carat — the lowest here — yet it measures 38% needle coverage with 32% open quartz and a brightness of 120 out of 255, which puts it among the two or three clearest in the collection. On clarity it belongs with the expensive stones; on price it does not.

What the photograph shows

The material is tourmalinated quartz — colourless rock crystal with black tourmaline needles grown inside it before the crystal closed around them.

A large open window of clear quartz across the centre and left of the face, with a fan of bold black needles radiating across it and a denser cluster gathered along the right edge. The contrast between the open area and the needles is the strongest on this page.

Wearing it

Three and a half carats is a modest ring stone or a small pendant. Quartz is 7 on the Mohs scale — genuinely hard-wearing, and a sensible first stone.

Care

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

This particular stone

This listing is one natural moh-e-najaf with a weight of 3.5 Carat. Its price is Rs. 1,310 — roughly Rs. 374 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0001 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.
