What drives the price of tanzanite
- Colour matters most. Strong, saturated blue or violetish blue is the most valuable; lighter, pastel stones cost less.
- Size. Larger stones show deeper colour and are rarer, so the price per carat usually rises with size.
- Cut. A well-cut stone returns light evenly; poorly cut stones are worth much less.
- Clarity. Most tanzanite is eye-clean. Visible inclusions or fractures lower the price.
- Matched pairs. Two stones matched for size and colour, ideal for earrings, take time to find and are priced accordingly.
Labels such as “AAA” are set by each seller; there is no official tanzanite grading scale. Compare stones by colour, size, cut and certificate, not by label. Learn more in our complete tanzanite guide.

Frequently asked questions
How much is tanzanite per carat?+
It depends mostly on colour and size. In our Moshi shop, loose blue-violet tanzanite currently ranges from $450 to $600 per carat. Deeper, more saturated colour and larger stones cost more per carat.
Why do bigger tanzanites cost more per carat?+
Tanzanite usually needs some size to show deep, saturated colour, and large clean crystals are rarer. So the price per carat tends to rise with size, not just the total price.
Is tanzanite cheaper in Tanzania?+
Buying in Tanzania puts you close to the only source, so you can see many stones and buy directly from the people who source and cut them. Always compare like for like: colour, size, cut and the certificate that comes with the stone.
How is the total price of a tanzanite calculated?+
Total price = carat weight × price per carat. For example, a 4.35 ct stone at $499 per carat costs $2,170.65. We show both numbers on every stone.
Do your prices include a certificate?+
Yes. Every stone comes with a GIA certificate and our own Gemstone Cutter (T) Investment certificate.
