A natural blue sapphire of 4.10 carats, about 4.51 ratti, at Rs. 14,350 – roughly Rs. 3,500 per carat, near the bottom of our current range. Our record gives its colour as deep blue.

Why a pendant suits a stone this size

Four carats is where a sapphire starts to become a lot of stone for a finger. On a ring it stands high, catches on sleeves and takes knocks from every direction; hanging at the chest it is protected on all sides and seen properly.

There is an optical reason too. A pendant setting can leave the back of the stone open, so light passes through the pavilion and comes back out at the eye. A deep blue sapphire benefits from that more than most stones: in a closed ring mount a dark blue can look almost black, where open-backed it reads as the colour it actually is.

Value at this rate

This rate sits near the bottom of our current blue sapphire band, which reaches about Rs. 15,000 per carat at the top. Four carats of deep blue sapphire at this rate is a lot of stone for the money; the trade-off is that you are not buying the finest end of the colour and clarity range.

Corundum and hardness

Sapphire is corundum, Mohs 9, second only to diamond among stones in ordinary use. A pendant sees far less abrasion than a ring in any case, so this one should stay bright with very little effort. It is still brittle at an edge, so avoid knocks and ask for a bail and setting that hold it securely.

What has not been tested

This particular stone

This listing is one natural sapphire, known in Urdu as Neelam, with a weight of 4.1 Carat. Its price is Rs. 14,350 — roughly Rs. 3,500 for each carat. Treatment: treatment not tested. Quote reference GS-000879 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.
