The Tanzanite

Found in the mountainous terrain of Mt. Kilimanjaro – the only place in the world where these gems are found – the tanzanite continues to gain popularity and rarity as time goes on. Originally, it comes from the mineral family of Zoisite and was discovered in 1967. The famous New York jewelers Tiffany & Co., named the stone Tanzanite. In 2002 it became the birthstone of December and the first stone to be added to the American Gem Society list since 1912.

Tanzanite is a gem that needs to be treated with love and care, as it is a fairly brittle stone. The three main colors that make up tanzanite are dark blue, red-purple and green-yellow. The darker it is, the rarer it gets, and therefore drives up the value. A majority of the stones need to be heat-treated to bring out its exquisite blue lavender color.

This gem has become one of the most sought-after stones of its time. However, this comes with the great fear of its extinction. The mines are being exhausted and have a predicted life span of 10 to 15 years, already making it 1000 times rarer than diamonds.
