Tanzanite's symbolism

Tanzanite is the gemstone for intuition and perception. It’s thus a great gemstone for consciousness and sensuousness and is a rare gemstone, said to help remove old patterns and manifest powers for better endeavours.

Tanzanite's history

Tanzanite is only found in one place on earth and is a relatively new discovery. Tiffany & Co. named this blue-violet variant of zoisite in honor of Tanzania where the gemstone was discovered in 1967. The tanzanite’s beautiful colour is activated by heat, and was thus only discovered after lightning struck the otherwise dull brown stone, and made the gemstone shine in a rare violet blue hue. 

A pleochroic gemstone

Tanzanite is a pleochroic gemstone, meaning that it shows different colours depending on which angle from which it’s viewed. Since tanzanite shows different colours, its possible for stonecutters to obtain the colour of their choice, by cutting the gemstone in a certain angle. 

Tanzanite can be found in an array of blue hues from violet to royal blue to purple.


Tanzanite is the blue-violet variant of zoisite. Tanzanite is a 6,5-7 on Mohs’ Hardness Scale, which measures gemstones’ hardness on a scale of 1-10, and is then about the same hardness as a quartz stone. 

Tanzanite is only found in Tanzania, high up in Mount Merelani, which sits at the foot of Mount Kilimanjaro.
