43.05 carats — 47.31 ratti — at Rs. 6,450, about Rs. 150 per carat. The reference is GS-IR-0018. This is the second-heaviest stone in the category; only the 52.90 carat piece is larger.

What 43 carats actually means

Carat weight is a poor guide to size on a dense material, and tiger iron is dense — the iron content sees to that. A 43 carat tiger iron is noticeably smaller across the face than a 43 carat agate would be, and heavier in the hand than its footprint suggests. That weight is the first thing people notice when they pick one up, and it is worth knowing before you plan a setting: a pendant at this weight needs a proper bail and a chain to match.

What the photograph actually shows

Brightness reads 83 out of 255, among the brightest in this category. 71% of the measurable colour sits in the red band, but 53% of the surface still reads as near-neutral grey, which is a higher grey share than the stones immediately around it in weight. The look is a warm brown-and-red ground with fine amber threads running down it and broad softer grey areas between — quieter and more muted than the boldly striped 40 and 41 carat stones, and some people prefer exactly that.

Wearing it

A display piece or a pendant. At this weight a ring is realistic only on a large hand and with a wide, well-made bezel.

Durability and care

The quartz-rich layers run to about 7 on the Mohs scale, the iron-rich ones less. Over years the polish dulls along the metallic bands first. Warm water and a soft cloth; no ultrasonic cleaner.

This stone has not been tested, so the treatment line reads "not tested" rather than untreated, and no origin is documented for it. Message +92 308 887 3888 with any questions. The rest of the range sits in the iron tiger eye category.

This particular stone

This listing is one natural iron tiger eye with a weight of 43.05 Carat. Its price is Rs. 6,450 — roughly Rs. 150 for each carat. Treatment: treatment not tested. Quote reference GS-IR-0018 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.

Whoever you buy iron tiger eye 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 iron tiger eye 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.
