A 2.18 carat tanzanite is a comfortable size for a pendant or a pair of earrings. This natural stone from Tanzania has the blue-violet colour that made the gem popular.

How it wears

Tanzanite sits at 6 to 7 on the Mohs scale, which is fine for jewellery that sees few knocks. If you plan a ring, choose a protective setting and take it off before heavy work.

What to ask

The blue-violet tone of tanzanite is normally brought out by heating, and the result is permanent.

This particular stone

This listing is one natural tanzanite with a weight of 2.18 Carat. Its price is Rs. 9,000 — roughly Rs. 4,128 for each carat. Origin: Tanzania. Treatment: treatment not tested. Quote reference AG-000474 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 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, and because you pay on delivery you can look at the stone — or have it tested — before any money changes hands.
