Tanzanite has quickly taken the gemstone and jewellery trade by storm with its beautiful violet & blue hues. These colors closely resemble those of the some of the finest sapphires.
The name “Tanzanite” was given to these gemstones by the jewellery company Tiffany&Co who named them after the only country known to produce them.



Tanzanites when spared from treatment are what is known as a “trichroic” (three colored) gemstone or crystal and will display three distinct different colors depending on the angle it is viewed in. Typically showing a violet and a blue hue along the A & B Axis. Whereas the C Axis will display a burgundy red hue. When heated, the same tanzanite specimen will still display the violet and blue hue, but will lose the Burgundy red hue as it turns “dichroic” (two colored).

Tanzanite crystals belong to the orthorhombic crystal system and usually form into very well defined chisel shaped crystals. Back in 2020, two giant tanzanite crystals were found, the larger of the two weighing approximately 9.27kg, making it the largest tanzanite ever found!
