At 6.1 carats this violet-blue tanzanite can hold a pendant on its own, and that is where we think it looks best. A ring works too, but tanzanite is only 6 to 7 on the Mohs scale, so pick a protective bezel and keep the ring for occasions rather than daily wear. Earrings are the kindest choice of all.

Silver shows a violet-blue stone crisply, while gold gives it warmth. If you would like a custom silver ring designed around it, message us on WhatsApp and we can share ideas.

This particular stone

This listing is one natural tanzanite with a weight of 6.1 Carat. Its price is Rs. 12,380 — roughly Rs. 2,030 for each carat. Treatment: treatment not tested. Quote reference AG-000110 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 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.
