Introduction To Tanzanite


Tanzanite is exceptionally brilliant and is unique among gemstones for its multi-dimensional color.

Tanzanite reflects both blue and violet –  and it is this mix of colors (called pleochroism) that makes tanzanite unique.  It is formed in many different colors, ranging from light blues or lilacs to deep indigos and violets.

It was discovered in the 1960s and named in honor of Tanzania, the location of its discovery by the jewelers Tiffany & Co. The famous firm declared it to be “the most beautiful blue stone discovered in the last 2,000 years”.

Tanzanite is so rare because it is found and mined in a small area only four kilometers wide and two kilometers long at the foot of Mount Kilimanjaro in the Manyara region of Northern Tanzania.

According to gemologists , the circumstances that led to the gems formation 585 million years ago were so exceptionally unusual, that the likelihood of finding tanzanite anywhere else on earth is one in a million, making it a thousand times rarer than diamonds.

At the current rate of mining, the geologist also estimates that the available supply will be depleted at the largest mine –  TanzaniteOne Mining Ltd – within the next 25-30 years. As a result, tanzanite is known as the “gemstone of a generation” because this generation will be the last one able to be a tanzanites first time owner, before the supply is exhausted.
