This particular stone

This listing is one natural dur-e-najaf with a weight of 24.75 Carat. Its price is Rs. 3,750 — roughly Rs. 152 for each carat. Treatment: treatment not tested. Quote reference AG-000210 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, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
