Heating a Tanzanite – or Zoisite, its real scientific name – makes it possible to obtain a blue-violet to violet-blue, which is in great demand on the jewelry market. We have here a Zoisite (natural Tanzanite) from the same deposits as Tanzanite, very rarely offered in a natural version. A heated specimen shows two colors of pleochroism whereas an unheated specimen shows three because the yellow to yellow-green disappears after heating. Rare piece.

Zoisite Natural Tanzanite: Usually pale to dark green in color.
Zoisite is a mineral species found in Tanzania.
It is usually pale to dark green in color and as varied in color as tan, gray, yellow, brown, blue, purple, colorless, or pink. Two colors can coexist in the same room like blue and yellow, blue and pink or blue and green.
The mineral is usually found in metamorphic rocks, and it is a common component of regional metamorphic rocks.
It is also found in some metamorphic deposits and it can be associated with other minerals such as epidote, garnet and wollastonite.
Zoisite is primarily used as a gemstone, particularly in the tanzanite variety, which is a blue-violet variety of the mineral found only in Tanzania.
