Short on time? Here is the summary: 41.25 carats, 7 on the Mohs scale, natural iron tiger eye. Everything below is detail to help you choose well.

The weight is large for the family, which makes this a statement stone. It looks best in a plain, strong setting that does not compete with the shifting band of light the stone is known for. Silver suits it, and a bezel keeps the edges safe.

When the parcel arrives:

• Tilt the stone under a window and look for a smooth, continuous streak of light.
• Run a finger around the rim and underside to check for chips.
• If you have access to a jeweller's scale, check the weight.

On treatment, the family is generally not enhanced, but we would rather give you facts about this exact stone than a general line. Message us on WhatsApp quoting AG-IR-0016, and remember that independent lab testing is your choice. More stones are in the iron tiger eye category.

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.
