Ask any honest jeweller about topaz and the first thing they will say is that colour decides the question. Golden stones are mostly sold as they came from the ground, yet heating does create some topaz shades, and a careful buyer should find out which applies before paying. For this 3.8 carat piece we claim no more than we know.

What we can say: it is a natural topaz sold as pukhraj, with golden tones, a Mohs hardness of 8, listed at Rs. 8,630, about Rs. 2,271 per carat. Look at it against white paper in daylight, because yellow stones can seem quite different under warm bulbs.

The fuller history of any stone comes from a laboratory report, and independent testing can be arranged on request. Send a WhatsApp message to +92 308 887 3888 quoting GS-000496 and we will pass on whatever we have on file. If you want to see how it compares with other golden pieces, the topaz category lists them with their weights, and our authenticity page explains how certificates are handled.

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. 8,630 — roughly Rs. 2,271 for each carat. Treatment: treatment not tested. Quote reference GS-000496 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request.
