Fifteen carats is a lot of turquoise, and it shows in how the stone sits in the hand. This Irani feroza costs Rs. 4,500, about Rs. 300 per carat, which makes it one of the more approachable pieces in the range for anyone who wants real size without a large outlay.

The colour is a calm sky blue, the kind that earned feroza its place in Pakistani and Iranian jewellery for centuries. Tradition links turquoise with protection and calm, and many families give it as a gift for that reason. We pass that on as belief, nothing more.

It rates only 5 to 6 on the Mohs scale, so think of it as a stone to look after. A pendant or a ring worn on occasions will keep it looking fresh far longer than a ring worn through every kitchen and workshop job. Stay clear of perfume, bleach and long soaks in water.

Most feroza is hardened with resin, and this one falls in that commonly stabilised group; stones left unstabilised are rarer and dearer.

If you want a custom silver setting, the size gives a jeweller plenty of room to work with. More options live in the feroza category.

This particular stone

This listing is one natural feroza with a weight of 15 Carat. Its price is Rs. 4,500 — roughly Rs. 300 for each carat. Origin: Iran. Treatment: treatment not tested. Quote reference GS-00026 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 feroza rates 5 to 6. That makes it soft for a gemstone, better suited to pendants, earrings and rings for special occasions than to a daily ring. Keep it away from perfume, cleaning products, steam and ultrasonic cleaners, and polish it with a dry, soft cloth after wear.

Whoever you buy feroza 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 feroza for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request. As general background (not a statement about this stone): Most turquoise (feroza) is stabilised with resin to harden it; natural, unstabilised feroza is rarer and costs more.
