Tanzanite - Decembers Birthstone. 

The weather might be cold but Tanzanite is so hot, it was the first gemstone added to the birthstone list since 1912 by the American Gem Trade Association in 2002.  Because tanzanite was only discovered in 1969, it never had a chance to be included in the official birthstone list, which was created in 1912.  Tanzanite was added  as it is by far the most popular blue gemstone after sapphire. Additionally it is commmonly used in fine jewellery, unlike the other blue stones - zircon and turquoise - which it shares Decembers birthstone status with. .

Be Born to Tanzanite. 

Fittingly tanzanite's heritage is a story underpinned by an age-old Maasai affinity with the color blue, regarded as sacred, healing and above all representative of new life. Based on this tradition , many people now see tanzanite as "the" birthstone -  irrespective of the month,  and give this beautiful stone as a gift at the beginning of life to celebrate new life and new beginnings.
