Sapphire is the second hardest of the common gems, rating 9 on the Mohs scale, and this 4.72 carat purple sapphire from Kashmir inherits that toughness. For buyers who want a ring that survives daily life, this is the most important fact about it, ahead of colour and ahead of price.

Because it is so hard, it resists scratches from dust and from other stones, and it can be worn on an active hand. The usual advice remains: protect the edges with a closed setting, and keep it in its own pouch. A soft brush with warm soapy water cleans it well.

The stone itself is purple and listed at Rs. 7,500, or about Rs. 1,589 per carat, under reference GS-00099. Purple sapphire is frequently fired to refine its colour, and stones that never were are harder to find. Ask us on WhatsApp what we know of this exact stone, and have it tested independently if you wish; we can arrange that on request.

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 purple 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 purple 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 purple sapphire for those three points before it is listed, a certificate is available on request, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
