15.40 carats, or 16.92 ratti, at Rs. 2,330 — roughly Rs. 151 per carat, which is the lower of the two rates running through this category. The reference is GS-IR-0003.

What the photograph actually shows

This one is worth describing carefully, because it is not the stone most people picture when they hear "tiger iron". It reads 57 out of 255 in brightness, and only 14% of its measurable colour falls in the red band, among the four lowest red readings in this category. What dominates instead is a cool blue-black with steel-grey layers; 43% of the surface measures as near-neutral. The bands are there, running the length of the stone, but they are dark on dark rather than red on grey.

It is also the narrowest cut here, at a width-to-height ratio of 0.55, so it reads as a long, slim oval rather than a rounded one.

Who it suits

If you want the classic red-and-gold tiger iron, buy further up this page. If you want something near-black with a quiet metallic shift in the light, this is the most interesting stone in the category, and it is among the cheapest per carat. Those are two different buyers and we would rather say so than sell the first one this stone.

Wearing it

The long oval shape sits well lengthwise along a finger and suits a narrow silver bezel. At 15.40 carats it has presence without bulk. Dark stones and oxidised silver work particularly well together; against bright polished silver the contrast can be stark.

Durability and care

Around 7 on the Mohs scale through the silica-rich bands, softer through the iron-rich ones. Clean with warm water and a soft cloth, avoid ultrasonic cleaners, and remove it before heavy work.

This particular stone

This listing is one natural iron tiger eye with a weight of 15.4 Carat. Its price is Rs. 2,330 — roughly Rs. 151 for each carat. Treatment: treatment not tested. Quote reference GS-IR-0003 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.
