A natural tanzanite of 4.25 carats, about 4.67 ratti, at Rs. 20,630 – roughly Rs. 4,854 per carat. Its colour is recorded as Blue.

Why a pendant is the right answer for tanzanite

This is not sales copy. It is the single most useful thing to know about the gem.

Tanzanite is Mohs 6 to 7, softer than sapphire. More importantly it has perfect cleavage in one direction: a plane inside the crystal along which a knock can split it cleanly, however hard it is. Rings get knocked. Pendants, hanging clear of everything, almost never do.

So the same stone that would need a protective bezel and careful handling on a hand will sit on a chain for decades with nothing worse than an occasional wipe. If you want tanzanite and you want to stop worrying about it, this is the way to own it.

Two practical notes: ask for a bail that holds the stone without pressure, and tell whoever sets it not to use an ultrasonic cleaner or steam, and to avoid torch heat near the stone.

At this size and rate

Four and a quarter carats is a good pendant size – enough presence to read as a real stone, not so much that it needs a heavy chain. At Rs. 4,854 per carat it is the second dearest per carat of the nine here.

In tanzanite a higher rate usually means better colour. We cannot show you that: the photograph on this listing is a catalogue image shared across all nine tanzanite listings on this site, not a picture of this stone. Message us for photographs and a video of the actual stone before committing at this price.

Treatment and testing

Rough tanzanite is usually brown, and almost all tanzanite is heated to produce its blue-violet colour: standard, stable, permanent. For this stone the treatment has not been tested and there is no laboratory report. Two of the names supplied for this category claimed certification and were refused for exactly that reason. We will arrange independent testing if you want it.

Where it comes from

Commercial tanzanite comes from one deposit on earth, in the Merelani Hills of Tanzania – a fact about the species, not paperwork for this stone.

This particular stone

This listing is one natural tanzanite with a weight of 4.25 Carat. Its price is Rs. 20,630 — roughly Rs. 4,854 for each carat. Origin: Tanzania. Treatment: treatment not tested. Quote reference GS-000476 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, 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.
