  • Rich green coloration, often caused by iron or chromium

  • Columnar or prismatic crystal structure

  • Embedded in a host rock, commonly quartz, feldspar, or mica schist

  • Metamorphic rocks like schist

  • Regions such as Brazil, Afghanistan, Pakistan, Madagascar, and parts of the U.S.

Why collectors like it

  • Strong pleochroism (color shifts depending on viewing angle)

  • Excellent for jewelry due to hardness

  • Often found in striking, well‑formed crystals
