Light passes through this stone almost without notice, which is the whole point of Dur-e-Najaf. Held up to a window, a clear quartz of 25.9 carats looks like a drop of frozen water with sharp edges, and that glassy quality is what people mean when they praise it.

It is a substantial piece, and the price reflects the weight rather than any rarity: Rs. 3,750, or about Rs. 145 per carat. Hardness is 7 on the Mohs scale, enough to resist everyday dust, though not immune to chips at the edges if it is dropped on tile.

Dur-e-Najaf is the name Pakistani buyers use for it, and in tradition it is worn for its association with purity and with the city of Najaf. We pass on that tradition without promising any outcome. The stone is generally left as nature made it, but ask us on WhatsApp about this exact one; independent lab testing is available.

The reference is GS-000209. You will find similar stones in the Dur-e-Najaf collection, and cash on delivery lets you inspect before paying.

This particular stone

This listing is one natural dur-e-najaf with a weight of 25.9 Carat. Its price is Rs. 3,750 — roughly Rs. 145 for each carat. Origin: Pakistan. Treatment: treatment not tested. Quote reference GS-000209 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.

Above twelve carats you are into collector territory. Pieces this heavy are usually set as pendants or kept loose, and they are prized for the size of rough they came from. If you do set it, choose a bezel or a heavy claw to protect the edges.

On the Mohs scale dur-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 dur-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 dur-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.
