Almost 5 carats of tanzanite is a generous size, and that is why this stone stands out. For the species, 4.9 carats counts as a larger piece, and a stone like this has the presence to be the centre of a pendant on its own. At Rs. 16,880 it works out to about Rs. 3,445 per carat.

The stone is a natural tanzanite from Tanzania, showing a blue-violet colour. Colour in tanzanite is normally developed by heating, and that step is routine and lasting in the trade. Ask us on WhatsApp if you want to know more about this one, or request independent lab testing.

Care and wear

Tanzanite is 6 to 7 on the Mohs scale. A bigger stone is also a bigger target, so a pendant or earring setting protects it best; a ring should have a deep bezel. Avoid sudden temperature changes and strong chemicals, and wipe it with a soft damp cloth.

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 tanzanite rates 6 to 7. That is middle-of-the-road hardness: comfortable in pendants and earrings, and in rings worn with some care. Store it apart from harder stones so it does not pick up scratches, and wipe it with a damp cloth rather than scrubbing.

Whoever you buy tanzanite 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 tanzanite 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.
