For jewellery, small-to-mid sizes are the sweet spot with moh-e-najaf, and at 4.25 carats this one sits right there: large enough to show its inclusions properly, small enough to wear comfortably on a finger.

With this stone, the thing to study is the interior. Moh-e-najaf is quartz holding fine needle-like crystals, and its appeal comes from how they lie. Some stones show a few bold lines, others a soft haze. Neither is better in absolute terms; it comes down to what you like. Be cautious of a perfectly clean interior in a stone sold under this name.

The weight is modest, so this is a ring or pendant stone rather than a feature piece. Quartz is 7 on the Mohs scale, tough enough for regular use with simple care.

The family is generally not treated, but the history of this exact stone can be confirmed if you message us on WhatsApp quoting AG-MO-0005. Independent lab testing is your choice. Similar stones are in the moh-e-najaf category.

Clean it with warm soapy water and keep it in a soft pouch.

Inspect the stone at your door before you pay. Karachi usually receives orders in 1 to 2 working days, other cities in 2 to 4, and you have 7 days to return it unused. Before you choose, read our moh e najaf guide.

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.
