A natural yellow sapphire – pukhraj – of 3.40 carats, about 3.74 ratti, at Rs. 25,500 – Rs. 7,500 per carat.

What yellow sapphire is

Sapphire is corundum, crystalline aluminium oxide. Blue is the colour people associate with the name, but corundum occurs in almost every colour, and the yellow one is pukhraj. Only red corundum gets a separate name – ruby. Everything else is sapphire with a colour in front of it.

At 9 on the Mohs scale sapphire is the hardest thing you can wear in a ring short of diamond, and that is the practical reason to choose it. Quartz, which most airborne grit is made of, sits at 7 and cannot scratch it. A pukhraj in daily wear will still look sharp in ten years, which is not true of softer yellow stones like citrine or yellow topaz.

Colour, from our record rather than the picture

Our record for this stone gives its colour as golden yellow. We are quoting the record rather than describing the photograph, and the next section explains why.

About the photograph

The image on this listing is a catalogue photograph of a yellow sapphire, not a photograph of this individual stone. The same picture, in slightly different crops, appears across this category. We would rather say that than let you infer the cut, the proportions or the exact tone of this stone from a picture that is not of it.

Message us on WhatsApp quoting GS-000472 and we will photograph and film this exact stone before you commit to anything.

Heating, said plainly

Most yellow sapphire is heated to deepen and even out its colour. That is standard for the stone, it is stable and permanent, and it is not a defect; unheated sapphires exist and command a premium precisely because they are less common.

For this piece: the treatment of this stone has not been tested and there is no laboratory report. If heated-versus-unheated matters to you – and on a stone at this price it reasonably might – ask us and we will arrange independent testing before you buy.

This particular stone

This listing is one natural yellow sapphire, known in Urdu as Pukhraj, with a weight of 3.4 Carat. Its price is Rs. 25,500 — roughly Rs. 7,500 for each carat. Treatment: treatment not tested. Quote reference GS-000472 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 yellow sapphire rates 9. 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 yellow sapphire 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 yellow sapphire 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.
