This 6.3 carat tanzanite is meant for someone who wants one bold violet-blue stone for a pendant or an occasion ring, and who is willing to handle it a little more gently than a sapphire.

What the price is telling you

With tanzanite, colour sets the price: the more clearly blue and violet show together, the more a stone is worth. This one has a violet-blue body colour, and its price sits well above the smaller, paler tanzanites for that reason. Nearly all tanzanite on the market has been gently heated to bring out the colour, and the result is permanent, so heating is simply the gem's normal condition rather than a flaw. To hear what we know about this exact stone, message us on WhatsApp quoting AG-00033. You are free to have it tested independently if you would like a written opinion before spending this much.

Wearing it and looking after it

Tanzanite measures 6 to 7 on the Mohs scale. That is fine for a pendant or earrings, but a ring worn every day will meet door frames and kitchen counters, so choose a setting with a raised rim, or keep the ring for dinners and occasions. Clean it with a soft damp cloth and store it apart from harder stones. To compare other pieces, browse the tanzanite collection.

Cash on Delivery lets you open the box and judge the colour yourself before paying; Karachi usually receives it in 1–2 working days, other cities in 2–4, with 7 days to return. Read our tanzanite guide as well.

This particular stone

This listing is one natural tanzanite with a weight of 6.3 Carat. Its price is Rs. 47,250 — roughly Rs. 7,500 for each carat. Treatment: treatment not tested. Quote reference AG-00033 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.
