A loose 4.35 carat Moh-e-Najaf — 4.78 ratti — at Rs. 1,950, about Rs. 448 per carat. The reference is GS-MO-0007. It is sold unset.

Why the rate is higher here

Rs. 448 per carat is above the Rs. 374 to Rs. 386 that most stones on this page cost. Only one other stone in the collection is priced at this level. The reason is the clarity: needle coverage reads 35% with 29% open quartz, which puts it among the three most transparent stones here, and open material of this kind is harder to find than densely included material.

Worth knowing, because at a glance the stones in this category look similar and the price differences are not arbitrary.

What the photograph shows

The material is tourmalinated quartz — colourless rock crystal with black tourmaline needles grown inside it — and on this stone the needles stand well clear of one another.

This one is pictured held in tweezers rather than resting on the backdrop, which is how we photograph a stone when the light passing through it is the point. You can see the needles standing clear against a bright field rather than against white paper — a better guide to how it will look set with an open back.

Buying it loose

Unset is the sensible route for a stone where transparency matters, because the setting decides how much light reaches it. Ask your jeweller for an open-backed bezel or a mount with a window; a closed bezel on a transparent quartz throws away the thing you paid for.

Wearing it

Four and a third carats suits a ring or a pendant. Quartz is 7 on the Mohs scale and takes daily wear well.

Care

Warm soapy water and a soft brush. 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 for exact dimensions before commissioning a setting. 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 4.35 Carat. Its price is Rs. 1,950 — roughly Rs. 448 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0007 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.
