What is Tanzanite ?

 

 

Tanzanite is a blue-violet variety of the mineral zoisite. Its colors vary from deep, dark royal blue with flashes of red to light cornflower or periwinkle blue. The deepest blues are the rarest and have more value than the light-colored tanzanite. The flattering cornflower blue and lilac shades are popular and affordable options.

Tanzanite gemstone is famous for having multidimensional color and being exceptionally brilliant. It exhibits a strong amount of pleochroism, meaning that it appears different colors when viewed from different angles. Tanzanite has a special three-dimensional version of pleochroism, making it a trichroic specimen. This gem shifts between shades of blue, violet and burgundy.

Tanzanite has a single source in Tanzania. Recently, deeper mining practices have unearthed extremely rare pink, orange, yellow and green varieties of Tanzanite Blue tanzanite undergoes a mild heat treatment to enhance its color. However, this process merely complements the natural geological process, and there is no chemical or structural difference between heated and unheated tanzanite.

Location: Tanzania

The world's only known source of tanzanite was discovered deep in the foothills of Mount Kilimanjaro in Tanzania, East Africa in 1967. Geologists say the chemical environment required to form this gem is so unique that the probability of mining tanzanite from another source is less than one in a million. The quality and quantity of gem deposits vary and the production of sellable rough is not consistent at all depths. If other deposits are not located (and that seems unlikely), geologists estimate the original supply of tanzanite will dry up within 30 years.
