Clear quartz is one of the most widely found gems on earth, and that is good news for anyone who wants a Dur-e-Najaf. A 16.4 carat stone like this one is priced on its size and clarity rather than on scarcity, which keeps it within reach of almost any budget.

It is colourless and transparent, and it rates 7 on the Mohs scale. Stones in this family are not usually treated, but message us on WhatsApp about this exact piece and we will tell you what we know. You are welcome to have it tested independently.

Choosing a setting

A transparent stone looks its best when light can enter from behind, so an open-back silver mount beats a closed one here. At this weight a ring will sit comfortably on a broad finger; on a slimmer hand a pendant may be easier to wear every day.

Pay the rider only after you have opened the box and seen the stone; Karachi usually gets it within 1–2 working days, other cities within 2–4, and returns are open for 7 days. Do read our Dur-e-Najaf guide.

This particular stone

This listing is one natural dur-e-najaf with a weight of 16.4 Carat. Its price is Rs. 3,380 — roughly Rs. 206 for each carat. Treatment: treatment not tested. Quote reference AG-000208 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.
