A natural topaz of 3.60 carats, about 3.96 ratti, at Rs. 15,000 – roughly Rs. 4,167 per carat. Its colour is recorded as light blue.

A practical size

At 3.60 carats this is one of the smallest stones in this category, where the largest is 18.95. For jewellery worn every day that is the point. A stone this size sits flat in a pendant, works as a single stone in a ring without overwhelming the hand, and is light enough for earrings. It is also the size most jewellers can set from stock mounts, which keeps the making charge down.

It is a near-square cushion, about 1.17 times as long as it is wide, brilliant-faceted, filling about 84% of its bounding box.

About the rate, which is high for its size

Worth explaining rather than hiding. At Rs. 4,167 per carat this is one of the dearest stones per carat in the category.

The reason is not that it is a finer stone. It is that this listing and three others are all priced at a flat Rs. 15,000 before discount regardless of weight – so the smallest of them carries the highest rate per carat. On total price it is in the middle of the category; on rate it looks dear. Judge it on the total, and ask us if you want a bigger stone for the same money, because this category has them.

What it looks like

About 82% of its face reads as blue and 40% as a strong saturated blue, with roughly 16% near-colourless. Its recorded colour is light blue, and that is a fair description: clearly blue, not deep.

It was previously titled Natural Yellow Topaz (Sunehla). Sunehla is the Urdu name for yellow topaz, and nothing in this category is yellow.

Treatment

Almost all blue topaz is irradiated and then heated. Natural blue topaz is rare and faint; the blues on the market begin as colourless topaz, are irradiated and then heated to fix the colour, which is permanent. For this stone the treatment has not been tested and there is no laboratory report.

Mohs 8, and the cleavage

Topaz is 8 on the Mohs scale and still has perfect basal cleavage – a plane along which a knock can split it cleanly. For a piece worn daily that is the governing fact: a bezel over claws, off the hand for housework, and never an ultrasonic cleaner. A pendant or earrings avoid the problem almost entirely.

This particular stone

This listing is one natural topaz, known in Urdu as Sunehla, with a weight of 3.6 Carat. Its price is Rs. 15,000 — roughly Rs. 4,167 for each carat. Treatment: treatment not tested. Quote reference GS-000488 when you message us about it. The photographs show this exact stone, so what arrives at your door is the piece you chose on screen.

Between two and six carats is the range most people choose for a gents' ring or a noticeable pendant. Here colour drives the price more than size does, which is why two stones of near-identical weight can be priced very differently.

On the Mohs scale 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 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. We check every topaz for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
