At 7.2 carats this amethyst is a mid-to-large stone for the family. Amethyst is one of the more generous gems in size, because the rough comes in good lengths, so 7 carats is a comfortable size for a man's ring and unmistakably large on a ladies' finger.

What that means in practice

A bigger stone shows its colour from across a room, but it also catches more knocks, so choose a setting with a rim that covers the edge. The stone has a laser cut and a purple colour. Hardness is Mohs 7, so everyday wear is possible, though quartz dust will gradually dull the surface if it is neglected.

It is listed at Rs. 15,000, or about Rs. 2,083 per carat. That per-carat figure is useful for comparing with smaller stones: in amethyst the rate often falls as the weight rises, so a larger stone is not automatically dearer per carat. Reference GS-000224.

When looking at any amethyst, check that the purple is even and hold it against a window to see how clear the body is. A few stones are warmed to lighten them, so ask what we know about this piece on WhatsApp. More examples sit in the amethyst category.

This particular stone

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

On the Mohs scale amethyst 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.
