Start with the origin: Madagascar, where a large amount of today's yellow sapphire is mined. This 2.05 carat pukhraj comes from there, and it is priced at Rs. 22,500, or about Rs. 10,976 per carat.

Because treatment matters in sapphire, we would like to be clear about what is normal. Most pukhraj is heated to improve and steady the colour, and stones that have not been heated are rarer and fetch a premium. We cannot assume which applies to a particular stone, so message us on WhatsApp and we will tell you what we know about GS-000446. A lab test can be arranged on request.

Next, what we know about the stone itself: it is a natural yellow sapphire of 2.05 carats, with a Mohs hardness of 9. That puts it among the toughest stones used in jewellery, so a ring setting is a realistic choice and you will not need to baby it.

When you collect it on Cash on Delivery, open the parcel, look at the stone under daylight and decide there and then. Compare more sapphire in our yellow sapphire collection.

Pay Cash on Delivery once you have opened the parcel and seen the stone yourself, anywhere in Pakistan, with 7 days to return it if you change your mind. Before you choose, read our yellow sapphire guide.

This particular stone

This listing is one natural yellow sapphire, known in Urdu as Pukhraj, with a weight of 2.05 Carat. Its price is Rs. 22,500 — roughly Rs. 10,976 for each carat. Origin: Madagascar. Treatment: treatment not tested. Quote reference GS-000446 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.

We sell natural stones only and inspect each one before it is listed. Treatment for this stone: Treatment not tested. Certificate available on request. As general background (not a statement about this stone): Most yellow sapphire (pukhraj) is heated to deepen and even out the colour; unheated stones exist and command a premium. Ask us on WhatsApp and we will tell you what we know about this exact stone; independent lab testing is available on request.

A certificate of authenticity is available on request for this stone, and independent laboratory testing can be arranged. Because you pay on delivery, you can also take the stone to a lab of your choice within the 7-day return window. Read more on our authenticity page.
