Tanzanite is a blue to violet variety of the mineral zoisite (Ca₂Al₃(SiO₄)₃(OH)), discovered in 1967 in Tanzania. Most tanzanite on the market is heat-treated to enhance color, as the natural form often appears brownish. It displays strong pleochroism, showing different hues from blue to purple depending on the viewing angle. The only known source is the Merelani Hills near Mount Kilimanjaro. Tanzanite is highly valued for its rarity, intense color, and clarity. This page explores tanzanite’s properties, origin, and significance in gemology and collecting.
