A natural blue sapphire of 2.65 carats, about 2.91 ratti, recorded as coming from Ceylon, at Rs. 13,250 – roughly Rs. 5,000 per carat. Our record gives its colour as deep blue.

Two stones, same weight, different prices

This tray currently holds another blue sapphire of exactly 2.65 carats priced at well over twice this one's rate per carat. Nothing about that is irregular, and it is worth understanding rather than wondering about: sapphire is priced on colour and clarity, not on weight, so two stones of identical weight routinely differ several times over in price.

What it means in practice is that carat weight tells you almost nothing about what a sapphire should cost. The rate per carat is the comparison to make, and then only against stones you have actually seen.

Ceylon

Sri Lanka, known in the trade as Ceylon, is the oldest continuously worked sapphire source in the world. The name covers a very wide quality range and tells you about geography rather than grade. It is the origin our record holds for this stone; it is not a laboratory origin determination, which is the only method that settles the question.

Size and wearing

At a shade under three ratti this is a practical everyday ring size: enough presence to be the point of the ring, not so much that it stands proud and catches. Silver and white gold both keep the blue cool.

Hardness

Corundum is Mohs 9, harder than anything you meet in daily life bar diamond. That is why neelam survives decades of wear where softer stones go cloudy. It remains brittle at an edge, so avoid knocks and ask for a setting that shields the girdle.

What has not been tested

No laboratory report, and the heating status has not been tested. Most blue sapphire is heated to improve colour and clarity. We will not claim this one is unheated, and we will arrange an independent test on request.

Care and ordering

Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners and steam while the treatment is unknown. One stone, sold once. Message us on WhatsApp for more photographs, and we deliver across Pakistan.

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 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.
