Prehnite, a translucent to transparent pale green mineral, belongs to the phyllosilicate group and was first identified in 1788, named after Dutch military officer Colonel Hendrik von Prehn. Commonly associated with minerals such as calcite and epidote, it predominantly occurs in basaltic environments. Notable for its diverse crystal habits—from prismatic and tabular to botryoidal shapes—prehnite is valued in gemology for its lustrous surface and tranquil green coloration. Its properties make it a preferred material for crafting beads, cabochons, and detailed carvings within the jewelry and decorative arts sectors.
