Prehnite is a phyllosilicate mineral exhibiting a translucent to transparent pale green color, first formally identified in 1788 and named in honor of Colonel Hendrik von Prehn. The mineral is typically associated with calcite and epidote, forming in basaltic host rocks. Prehnite displays a range of crystal habits, including prismatic, tabular, and botryoidal structures, often producing a glossy, vitreous surface. Its optical properties, coupled with its appealing pale green coloration, make it a sought-after mineral in gemology and ornamental applications, particularly for beads, cabochons, and carved decorative pieces.
