Tanzanite, Turquoise & Zircon

December Birthstone


Tanzanite is a one-of-a-kind gemstone unlike any other and can only be found in one place on Earth: the foothills of Mount Kilimanjaro. This gem possesses an exotic velvety blue with a rich overtone of purple, a color unlike any other.

One of today’s most popular blue gemstones, Tanzanite comes in a variety of shapes, sizes and striking assortments of blue tones. Rarely pure blue, Tanzanite almost always displays its signature overtones of purple. In smaller sizes, Tanzanite usually contains lighter tones and the lavender color is more common. While in larger sizes, Tanzanite typically displays a deeper, richer and beautiful blue.




Turquoise signifies wisdom, balance and truth. It is said to be the stone of protection, possessing the power to prevent injury. For this reason, many travelers carry turquoise amulets.

Known and valued as a gemstone for thousands of years, the turquoise stone’s original sources, Egypt and Sinai, have exhausted their production and so most of today’s turquoise stones come from Iran. The stones were originally sent to Europe through Turkey. This explains the stone’s name, which means Turkish in French. The great appeal of this stone is its sky blue color, but because it is relatively soft, only 5 to 6 on the Mohs scale, it requires special care.
