Zoisite is a calcium aluminum sorosilicate that forms prismatic to tabular crystals with a vitreous to pearly luster. It commonly occurs in shades of green, blue-green, or brown, often displaying zoning along crystal faces and twinned habits in certain localities, and it can form in metamorphic skarns and serpentinite-related deposits. Notable specimens have come from Tanzania, Pakistan, Afghanistan, Norway, and the United States, where crystals exhibit sharp terminations and well-developed prism faces that thrill collectors of aural hues and distinct crystal shapes.

About Zoisite
Collectors value zoisite for its optical variety, including color zoning, pleochroism, and occasional gem-quality material when cut as tanzanite-like varieties. While gem forms are relatively rare outside of specific varieties, well-formed crystals with rich color and clean faces from historic or renowned localities attract attention in cabinets and display cases. The mineral’s broad locality spread and potential for striking crystal aesthetics make it a staple study piece for those building a curated mineral collection.
