A natural white topaz of 10 carats, about 10.99 ratti, at Rs. 20,000 – Rs. 2,000 per carat. A full ten carats, which is a satisfying number to own.

The most elongated stone here, which is what a pendant wants

Measured, this stone runs about 1.39 times as long as it is wide – the most elongated of the thirteen in this category, where the roundest measures 1.06.

That matters for a pendant specifically. A long oval hangs straight and reads as deliberate; a nearly-round stone of the same weight tends to sit like a button and to swing as you move. The extra length also gives the bail somewhere sensible to sit without crowding the stone.

A pendant is also the gentlest setting a topaz can have, which given what follows about cleavage is worth a moment's thought: a stone on a chain simply does not take the knocks a ring does.

Hardness is not toughness

Topaz is 8 on the Mohs scale, harder than the quartz dust in ordinary air, so it keeps its polish and its crisp facet edges.

But topaz has perfect basal cleavage – one plane along which the crystal parts cleanly if it takes a sharp blow. Hardness is about resisting scratches and has nothing to do with resisting breaks. In a pendant you are already most of the way to safe; just avoid ultrasonic cleaners, steam and sudden temperature changes. Warm water, mild soap and a soft brush.

Colour and finish

About 20% of its face carries a faint yellow-green cast, measured – on the cleaner side of this parcel, which runs from under 9% to nearly 39%. Its outline fills about 82% of its bounding box, a little fuller than the 78.5% of a perfect ellipse, so it reads as a generous long oval rather than a narrow one.

Treatment

Colourless topaz is usually untreated, unlike blue topaz, which is irradiated and heated as standard. That is about the material: 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.
