Tanzanite

Tanzanite is an exotic, vivid blue, kissed by purple hues. Legend has it that tanzanite was first discovered when some brown gemstone crystals lying on the dry earth were caught in a fire set by lightning that swept through the grass-covered hills. The Masai herders driving cattle in the area noticed the beautiful blue color and picked the crystals up, becoming the first tanzanite collectors.

 

Tanzanite has the beauty, rarity and durability to rival any gemstone. It is the ultimate prize of a gemstone safari. Tanzanite is mined only in Tanzania at the feet of the majestic Mount Kilimanjaro.

 

One of the most popular blue gemstones available today, tanzanite occurs in a variety of shapes and sizes and also provides a striking assortment of tonal qualities. Rarely pure blue, tanzanite almost always display its signature overtones of purple. In smaller sizes, tanzanite tends toward the lighter tones and the lavender color is more common. While in larger sizes, tanzanite typically displays deeper, richer color.
