Before the discovery of tanzanite, the known varieties of zoisite made little impact on the gem market. Discovered in the shadow of Mt. Kilimanjaro in 1967, tanzanites show both dramatic color change and pleochroism. In natural light, tanzanites can appear an almost sapphire blue. In fluorescent light, they may appear more violet or amethyst-like.

Tanzanites include only blue to violet zoisites. Thus, transparent, gem-quality zoisites in any other color should be called zoisites.

Other sources of gem-quality zoisites include:

  • United States: Massachusetts; South Dakota; Wyoming (greenish-gray material, sometimes tumble polished for jewelry).
  • Austria; Finland; Germany; Baja California, Mexico; Pakistan; Russia; Scotland.
