Buyers usually ask about moh-e-najaf before they ask about price, so here are the questions that come up most for this 4.85 carat piece.

What am I looking at?

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

Will it handle everyday wear?

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

Has it been treated?

Stones in this family are usually left alone, but we do not like to assume. Message us on WhatsApp quoting AG-MO-0010 and we will share what we know about this exact stone. Independent lab testing is your choice.

How do I look after it?

Warm water, a little mild soap and a soft cloth. Store it apart from harder gems.

How does buying work?

Cash on Delivery: you open the parcel, check the stone and only then pay. Karachi usually gets orders in 1 to 2 working days and other cities in 2 to 4, with 7 days to return it unused. More pieces are in our moh-e-najaf collection. Before you choose, read our moh e najaf guide.

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 AG-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. We check every moh-e-najaf for those three points before it is listed, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. No lab report yet; independent testing welcome.
