Hardness first: this 3.7 carat moh-e-najaf is quartz, and that gives it 7 on the Mohs scale. In plain terms, it resists scratching from dust and most everyday contact, so a ring is a sensible choice and not a risk.

It is still a small stone. A hard blow to the side can chip any gem, so a bezel or a closed setting keeps it safe, and it is better to remove a ring before gardening or lifting. Clean it with warm water and a little mild soap, rinse, and dry with a soft cloth. Ultrasonic cleaners are best left alone because the fine inclusions inside the stone can be disturbed by vibration.

The listing price is Rs. 1,430, about Rs. 386 per carat, and the reference is GS-MO-0003. The inclusions that define moh-e-najaf are part of what you are buying, so do not expect a glass-clear interior.

This particular stone

This listing is one natural moh-e-najaf with a weight of 3.7 Carat. Its price is Rs. 1,430 — roughly Rs. 386 for each carat. Treatment: treatment not tested. Quote reference GS-MO-0003 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.
