How would a 4.4 carat pukhraj look in a ring? A topaz of this size is neither shy nor showy, and sits comfortably on a finger, which is why it works well as a ring stone. At 8 on the Mohs scale it is hard enough for regular wear, and a closed-back bezel in silver keeps the corners safe. You could also hang it as a pendant, and a custom silver ring setting can be discussed on WhatsApp.

The stone is a natural yellow topaz, sold as pukhraj and sunehla. It costs Rs. 15,000, about Rs. 3,409 per carat.

Treatment first, always: golden topaz is mostly left as found, though other colours owe their tone to heating. Message us and we will say what we know about this stone, and an independent lab can test it if you ask.

To keep it bright, wipe it with a soft cloth after wearing and wash it occasionally in lukewarm soapy water. Keep it clear of sudden heat and harsh chemicals, and store it apart from harder stones.

This particular stone

This listing is one natural topaz, known in Urdu as Sunehla, with a weight of 4.4 Carat. Its price is Rs. 15,000 — roughly Rs. 3,409 for each carat. Treatment: treatment not tested. Quote reference GS-000491 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.
