People expect quartz to be the plainest thing in a gem box, and then they see what rutilated quartz does: thin needles of another mineral hanging inside clear crystal, giving a stone with far more to look at than its modest price suggests.

This 9.55 carat moh-e-najaf is the largest of the moh-e-najaf stones in this group, so its inclusions have plenty of room to show. It reads clearly across the hand, yet quartz is light for its size, so it will not drag on a finger the way a denser gem of the same carat weight might.

The Mohs rating is 7. That makes it a reasonable ring stone, and an easy pendant stone too, where it meets even less contact.

Quartz of this kind is usually sold as found. Message us on WhatsApp quoting AG-MO-0013 and we will tell you what we know about this particular piece; independent lab testing is your choice.

To compare needle patterns across different weights, look through the moh-e-najaf range.

A broad silver bezel suits a stone of this size, and a sturdy chain if you choose a pendant.

You pay in cash after opening the parcel and checking the stone. Karachi orders normally arrive in 1 to 2 working days and other cities in 2 to 4, with 7 days to return it unused. Before you choose, read our moh e najaf guide.

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

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.
