What is Tanzanite?

Very successful marketing from large jewellery companies ensures that people

believe Tanzanite should only be very deep blue! As you can see from the chart to the right,

the tones and saturations of colour within Tanzanite are glorious and varied.  Like Amethyst it ranges from palest Lavender through to deepest darkest blue.  Beauty is in the eye of the beholder, we believe.

Tanzanite is the blue/purple variety of the mineral zoisite.  Discovered in the Meralani Hills of in Northern Tanzania in 1967, near the city of Arusha and Mount Kilimanjaro.  It is used as a gemstone.

Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet and burgundy depending on crystal orientation, which makes it rather challenging to photograph.

Tanzanite can also appear differently when viewed under alternate lighting conditions.  The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination.

Tanzanite in its rough state is usually a reddish brown color. It requires artificial heat treatment to 600 °C in a gemological oven to bring out the blue violet of the stone. Tanzanite is a rare gem.  It is found only in the foothills of Mount Kilimanjaro.

Tanzanite, the birthstone for December, was introduced to the world by Tiffany's of New York in 1969.  They had exclusivity for 10 years! It has become an extremely popular gemstone for its beauty, its uniqueness and for investment (the larger carat weights).  It is the ONLY gemstone to have been added to the birthstone list since 1912!  It was added in 2003.


24 years - as well as being the birthstone for December it was added as a suggestion for a 24th Anniversary, be that a birthday or other special day!

The Gemstone of New Beginnings: Tanzanite has been attributed with qualities of good luck and prosperity and associated with celebrations of new life and new beginnings.
