40.85 carats — 44.89 ratti — at Rs. 6,150, about Rs. 151 per carat. The reference is GS-IR-0015. We call this one premium for a specific, measurable reason.

All three layers, clearly

Tiger iron is supposed to show three things: red jasper, metallic grey hematite and golden tiger's eye. Most of the stones in this category show two of the three, because the golden layer is the one most often missing. On this stone 13% of the measurable colour falls in the golden band — the second-highest gold reading in the category — alongside 54% in the red band, with only 23% of the surface reading near-neutral. Brightness is 79 out of 255.

That balance is what you are paying for. The face carries broad amber-gold bands running beside red jasper, separated by dark seams, and because a real tiger's-eye layer is present it has the silky shimmer that moves as you tilt the stone — the fibrous structure in that golden band is what produces it. The stones here without a measurable gold layer cannot do that, whatever else they have going for them.

Wearing it

Forty carats is a display piece or a heavy pendant. If you want the shimmer to show, mount it so the stone can be tilted — a pendant swings and catches the light far better than a ring, which mostly sits flat.

Durability and care

The quartz-rich layers run to about 7 on the Mohs scale, the iron-rich ones less, so the polish dulls first along the metallic bands. Warm water and a soft cloth; never an ultrasonic cleaner.

No testing has been carried out, so the treatment is recorded as "not tested" rather than untreated, and we hold no documented origin for this stone. Message +92 308 887 3888 with questions. Comparable pieces are in the iron tiger eye category.

This particular stone

This listing is one natural iron tiger eye with a weight of 40.85 Carat. Its price is Rs. 6,150 — roughly Rs. 151 for each carat. Treatment: treatment not tested. Quote reference GS-IR-0015 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 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.
