Just over forty carats: this iron tiger eye weighs 40.20, and its rate per carat is in line with the other large stones in the family, which makes comparison easy.

Stones above forty carats are not often worn as everyday jewellery, so they tend to become pendants or pieces bought simply to be admired. A broad face gives the band of light plenty of room to travel, and on a stone this size the movement is easy to see even from a short distance away.

Durability is good, with a hardness of 7 on the Mohs scale, but sheer size means it can still get knocked. Keep it in a padded pouch and take it off for sport or heavy work. Clean it with mild soap and water, then dry it thoroughly.

The family is generally not enhanced, and we will share what we know about this particular stone if you message us on WhatsApp quoting AG-IR-0013. Independent lab testing is your choice. More options are in the iron tiger eye collection.

A sturdy chain and a strong bail are essential if you go for a pendant.

Pay only after you have opened the parcel and seen the stone. Karachi usually receives orders within 1 to 2 working days and the rest of Pakistan within 2 to 4, with 7 days to return it unused. Before you choose, read our iron tiger eye guide.

On the Mohs scale iron tiger eye 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.
