Silver shows off blue well, costs less than gold and is easy to resize or rework later, which is why a custom silver ring is the most common home for a stone like this 2.45 carat natural blue sapphire. A bezel gives extra protection; open claws let in more light. Talk it through with us on WhatsApp, with no commitment.

It could also hang as a pendant, where its size is comfortable and its hardness of 9 on the Mohs scale means little risk of surface wear. Gold is the choice if you want a finish that lasts for decades.

The facts: 2.45 carats, blue, reference AG-000820. Its rate per carat looks high, and the small size is part of the reason; small sapphires are priced differently. Heating is common in sapphire, so ask us what we know about this stone. If you want independent testing, that is your choice.

When it arrives, compare the colour in daylight and under a lamp; a good blue stays lively in both.

In Vedic tradition neelam is linked with Saturn, and many people consult an astrologer before wearing it.

This particular stone

This listing is one natural sapphire, known in Urdu as Neelam, with a weight of 2.45 Carat. Its price is Rs. 12,380 — roughly Rs. 5,053 for each carat. Treatment: treatment not tested. Quote reference AG-000820 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 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 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 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.
