Moh-e-najaf is one of those stones buyers ask about before they ask about price, so here are the questions that come up most for this 4.85 carat piece, listed under reference GS-MO-0010. It costs Rs. 1,840, which is about Rs. 379 per carat.

What exactly am I looking at?

Rutilated quartz: quartz crystal holding needle-like inclusions. The needles are the character of the stone, not damage.

Will it survive everyday wear?

Quite well. It rates 7 on the Mohs scale, so ordinary dust will not scratch it, though a hard blow against a door frame can still chip any stone.

Has it been treated?

Stones of this family are usually left alone, but we do not like to assume. Ask on WhatsApp and we will share what we know about this exact stone, and lab testing is available if you want it independently confirmed.

How do I look after it?

Warm water, a little mild soap, a soft cloth. Store it apart from harder gems. More pieces sit in our moh-e-najaf collection if you want to compare.

This particular stone

This listing is one natural moh-e-najaf with a weight of 4.85 Carat. Its price is Rs. 1,840 — roughly Rs. 379 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0010 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.
