December birthstone – tanzanite

Significance and history

Legend has it that violent storms lit bushfires on the Merelani hills, not far from the famous extinct volcano, Kilimanjaro. The shepherds who had fled far from the disaster eventually returned: it was then that they discovered the blue pebbles, originally grey-brown, transformed by the heat into superb blue gems... Blue is sacred to the Masai.

Where can I find some? Origin

In Tanzania. This is still the only place in the world where it is mined. The mines are located on Masai territory, which owns 95% of the stone trade. 

Hardness & Care

Tanzanite has a hardness of 6.5 on the Mohs scale, which makes it relatively fragile, so it is important to take care when wearing it in a ring. To clean Tanzanite, use an old toothbrush with soap and lukewarm water. 

The ideal metal to go with your Tanzanite

Your Tanzanite will go equally well with warm or cool colours, white, pink or yellow gold or platinum.


Tanzanite is a symbol of happiness and prosperity. 

Tanzanite is said to have many beneficial effects on the brain and nervous system. It is said to improve hearing and sight, and to facilitate the work of the kidneys. It is said to soothe abdominal and stomach pains and to protect the skin and bones.
Tanzanite is said to stimulate the imagination and creativity, making it an ally of artists, writers, musicians and other creators. It increases memory capacity and intellectual curiosity. It lifts the soul in search of noble aspirations and an ever-deeper spiritual quest.
