A natural white topaz of 8.20 carats, about 9.01 ratti, at Rs. 16,400 – Rs. 2,000 per carat.

A broad stone for a gents' ring

Eight carats of topaz is a stone with presence. In a gents' silver ring that is roughly the size that fills the head properly without looking borrowed – big enough to be the point of the ring, not so big that it catches on everything. The oval shape covers more of the finger than a round of the same weight, which is usually what is wanted in a men's piece.

The liveliest stone in this parcel

Two measurements say the same thing about this one.

It carries the densest facet edges of the thirteen stones here – more facet junctions across its face than any other, which is what produces visible flash as the hand moves. And it shows the strongest colour saturation of the thirteen, with about 36% of its face carrying a visible yellow-green cast, close to the most tinted stone in the category.

So this is not the one to buy if you want an icy white; for that, look at the cleanest stone in this parcel, which measures under 9%. This one is a warmer, busier, more obviously alive stone, and against silver that warmth reads as character rather than as a fault. We would rather set that out than let you find it out when the parcel arrives.

Shape

An oval, measured against a true ellipse row by row, about 1.29 times as long as it is wide, filling about 80% of its bounding box where a perfect ellipse fills 78.5%.

Hardness, cleavage and care

8 on the Mohs scale, harder than everyday dust, so it keeps its polish. But topaz has perfect basal cleavage and will split on a hard enough knock in the wrong direction – a real consideration in a ring worn by someone who works with their hands. Ask for a bezel, take it off for heavy work, and keep it away from ultrasonic cleaners and sudden heat. Warm water, mild soap, a soft brush.

Treatment

Colourless topaz is usually untreated. That is about the material and not this stone: the treatment of this stone has not been tested and there is no laboratory report.

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 white topaz rates 8. Few materials will scratch it, so it copes well with everyday ring wear. A soak in warm water with a drop of mild soap and a soft brush keeps it bright; skip the ultrasonic cleaner if inclusions reach the surface.
