Tanzanite is the blue/purple variety of the mineral zoisite discovered in the Merarani Hills of northern Tanzania
in 1967, near the city of Arusha. It is a popular and valuable gemstone when cut, although its durability is somewhat lacking.
Tanzanite is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet, and sage-green depending
on crystal orientation.
Zoisite (Variety Tanzanite)
Tanzanite is the important gem variety of zoisite (zoisite is
also refered
to as epidote)
Color is variable. Gem varieties are often sapphire blue or violet blue.
However, other
colors occur, like the red variety (thulite), and a green
variety.
Hardness: 6.5-7 (note this hardness is less than
normally desirable for a
gem used in jewelry subject to abrasion by dirt and dust)
Crystal system: orthorhombic
Composition:
Ca-Al-silicate (tanzanite color is attributed to a Vanadium (V)
as an impurity strongly pleochroicView an uncut crystal.
Where
is it found?
The variety of zoisite known as tanzanite was discovered in Tanzania in
1967.
TANZANITE occurs
in pegmatite veins (inclusions suggest hydrocarbon-rich fluids) .
WE usually heat treated at 400 - 500 C to remove
brown tints,
deepen blue
-Some cats eye varieties due to channels or needles
-Best orientation for color not
same for chatoyancy
Clarity is the second most important of the 4 c's when considering Tanzanite
quality. Clarity
simply refers to how inclusion-free a gemstone is. Once
again, the most universally accepted and most documented system
is the GIA.
