A 26.9 carat Dur-e-Najaf has a lot of edge to protect. Quartz rates 7 on the Mohs scale, so it will scratch glass and ignore most household dust, but a drop on a hard floor can still chip a corner, and a bigger stone offers more corners to knock. That is why we suggest a pendant with a close-fitting bezel, and treating a ring as something for weddings and Eid rather than every day.

The stone is clear, transparent quartz with no added colour. Clear quartz is not usually treated, and if you message us on WhatsApp quoting AG-000211 we will tell you what we know about this exact piece. An independent lab test is available to you if you want one.

Looking after it

Wash it in lukewarm water with a little mild soap and dry it with a soft cloth. Store it in its own pouch, away from sapphire, topaz and other harder gems that could scratch it. Our gemstone care guide explains the general habits, and the Dur-e-Najaf collection has similar stones.

It travels Cash on Delivery, so you open the parcel and check it before paying; Karachi in about 1–2 working days, elsewhere 2–4, with 7 days for returns.

This particular stone

This listing is one natural dur-e-najaf with a weight of 26.9 Carat. Its price is Rs. 3,380 — roughly Rs. 126 for each carat. Treatment: treatment not tested. Quote reference AG-000211 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.
