"Heated" is the first word you will hear from any experienced jeweller about sapphire, and it is the honest starting point for this 6.00 carat natural blue sapphire too. Most sapphire sold anywhere has been through a furnace to improve colour and clarity, and stones that have not are rarer and priced higher. A careful buyer asks, and keeps asking until the answer is clear.

What we can tell you

This is a single neelam of 6.00 carats, hardness 9 on the Mohs scale, reference AG-000795. We do not hold a full treatment history for it, so message us on WhatsApp and we will tell you what we know and what we do not. That is the only fair way to answer.

At six carats it makes a ring with presence that is still comfortable to wear every day, and it would carry a pendant equally well.

If treatment matters to you

Where treatment status affects your decision, an independent lab test is the way to settle it, and you are free to arrange one. In Vedic astrology 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 6 Carat. Its price is Rs. 15,000 — roughly Rs. 2,500 for each carat. Treatment: treatment not tested. Quote reference AG-000795 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.

From six carats up a stone becomes the centre of attention. It wants a broader shank or a secure claw setting and suits an occasion ring, a signet or a centre pendant. Clean natural material of this size turns up far less often, and the per-carat rate reflects that.

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.
