Cleaning a sapphire rarely goes wrong, because at 9 on the Mohs scale it can take it. Warm water, a drop of mild soap and a soft brush will lift skin oils from this 2.15 carat pukhraj, and nothing more elaborate is needed. If it is set and you are unsure about the mount, ask your jeweller before trying an ultrasonic cleaner.

The stone is a natural yellow sapphire from Madagascar. At over two carats it makes a visible ring stone without needing a heavy mount.

Pukhraj is commonly heated to clean up and intensify colour, so ask whether this piece was. Message us on WhatsApp with reference AG-000450 and we will tell you what we know.

Store it in a soft pouch of its own, since a sapphire will scratch softer gems. Dry it after washing, because leftover soap leaves a film that dulls the sparkle. If it is mounted in a daily ring, check the claws every few months for looseness. Others like it are in the yellow sapphire category.

Nothing is paid upfront. The courier brings it to your door (1–2 working days in Karachi, 2–4 for most other cities), you check it, then hand over the cash, and a 7-day return window stays open after that. Our yellow sapphire guide covers the rest.

This particular stone

This listing is one natural yellow sapphire, known in Urdu as Pukhraj, with a weight of 2.15 Carat. Its price is Rs. 40,310 — roughly Rs. 18,749 for each carat. Origin: Madagascar. Treatment: treatment not tested. Quote reference AG-000450 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, 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. No lab report yet; independent testing welcome. 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.
