How white topaz is priced here, in full

This listing is about price, so here is all of it.

Every stone in this category is priced at exactly Rs. 2,000 per carat. From the smallest at 5.30 carats and Rs. 10,600 to the largest at 12.60 carats and Rs. 25,200, the rate does not move. We are not going to pretend some of them are finer than others to justify a spread, because on our own measurements they are a consistent parcel.

What that means for you is simple: in this category you are choosing size and shape, not grade. Multiply the carat weight by two thousand and you have the price. If you want to compare us with another seller, do the same sum on their listing – total price divided by carat weight. If a listing does not give you the weight, you cannot do that sum, and that is worth noticing.

White topaz is not a rare mineral, and nobody should sell it to you as one. It is popular because it gives the look of a bright white stone at a fraction of what a colourless sapphire or a diamond would cost, and because at Mohs 8 it is hard enough to live in a ring.

What this one is

An oval, and a properly cut one: measured row by row against a true ellipse, it is among the two closest to a real ellipse in this category. Its outline fills about 80% of its bounding box, where a perfect ellipse fills 78.5%. In practice that means it drops into a standard oval mount without a jeweller having to adjust the seat.

About 21% of its face carries a faint yellow-green cast, measured – on the clean side for this parcel, where the range runs from under 9% to nearly 39%.

Hardness, cleavage and care

Topaz is 8 on the Mohs scale, which resists scratching well. It also has perfect basal cleavage and can split on a sharp knock, which hardness does not help with. Bezel or protected claws, off for heavy work, no ultrasonic cleaner, no sudden heat. Warm water, mild soap, a soft brush.

Treatment

Colourless topaz is usually untreated, unlike blue topaz, which is irradiated and heated as standard. That is the material rather than this piece: 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.

Whoever you buy white topaz from, make sure of three things: the stone is natural rather than lab-grown, glass or glass-filled; any treatment is stated in writing; and the weight quoted is the weight of the finished stone.
