A natural white topaz of 9.45 carats, about 10.38 ratti, at Rs. 18,900 – Rs. 2,000 per carat.

What a stone this size suits

Nearly nine and a half carats is a statement stone. In women's jewellery that points away from a modest solitaire and towards a cocktail ring, a pendant or a substantial pair of earrings if you can find its match. A clear, bright, well-cut white stone at this size does the work that a much more expensive colourless sapphire would do, and nobody across a room is checking which it is.

It is also a practical choice in a way that a softer stone of this size would not be: at Mohs 8 it will not go cloudy from ordinary wear, which matters on a piece you intend to keep using rather than keep in a box.

A textbook oval outline

Measured, its outline fills 79.4% of its bounding box – and a perfect ellipse fills 78.5%. That makes it the closest of the thirteen stones here to a textbook oval outline: it is not fuller at one end, it is not squared off at the sides, it is simply an oval. It runs about 1.34 times as long as it is wide, which is a slightly elongated, elegant proportion rather than a stubby one.

The practical value is that it will drop into a standard oval mount without a jeweller cutting a seat specially, which on a stone this size saves real money on the setting.

Colour, measured

About 26% of its face carries a faint yellow-green cast – middling for this parcel, where the range runs from under 9% to nearly 39%. A bright near-white with a touch of warmth, rather than an icy stone.

Hardness, cleavage and care

8 on the Mohs scale. Harder than everyday dust, so it holds its polish. But topaz has perfect basal cleavage and can split on a sharp knock, which hardness does not prevent. On a pendant that risk is small; in a ring, ask for a bezel. No ultrasonic cleaner, no steam, no sudden heat. Warm water, mild soap, a soft brush.

Treatment

Colourless topaz is usually untreated. That is about the material, not this stone: the treatment of this stone has not been tested and there is no laboratory report. We will arrange independent testing on request.

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.
