A natural topaz of 3.80 carats, about 4.18 ratti, at Rs. 10,130 – roughly Rs. 2,666 per carat. Its colour is recorded as blue.

The liveliest faceting of the seventeen

Counting the share of the stone's face that sits on a sharp edge between one facet and the next – which is what makes a cut stone sparkle rather than glow – this one measures 40%, the highest of the seventeen stones in this category, where the quietest reads 9.9%. It is a small, busy, bright stone, cut with many facets for its size.

That is what you want in a piece you are making yourself: a stone that does the work in a plain setting instead of needing one built around it. Its outline is a long cushion, about 1.77 times as long as it is wide, and it occupies none of the corners of its bounding box – the cleanest curved outline in this category.

Colour

About 89% of its face reads as blue and 53% as a strong saturated blue, with roughly 8% near-colourless. Recorded as blue, and clearly blue in the hand.

This listing was titled Natural Yellow Topaz (Sunehla), which it is not. Sunehla is the Urdu name for yellow topaz; across all seventeen stones here the yellow share peaks at 2.46%.

Where the blue comes from

Almost all blue topaz is irradiated and then heated. Natural blue topaz is rare and very faint. The blues on the market begin as colourless topaz, are irradiated to create the colour and heated to stabilise it; the result is permanent and accepted throughout the trade. It is also why blue topaz is inexpensive, and why nobody should sell you one as a rarity.

For this stone the treatment has not been tested and there is no laboratory report.

Making something with it

Topaz is 8 on the Mohs scale but has perfect basal cleavage – a plane along which a knock splits it cleanly whatever its hardness. If you are setting it yourself: set it last, keep torch heat away, use a bezel for ring wear, and never clean it in an ultrasonic tank. Warm water, mild soap and a soft brush are enough.

This particular stone

This listing is one natural topaz, known in Urdu as Sunehla, with a weight of 3.8 Carat. Its price is Rs. 10,130 — roughly Rs. 2,666 for each carat. Treatment: treatment not tested. Quote reference GS-000492 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.
