Prehnite, a delicate pale green mineral exhibiting translucence to transparency, is classified within the phyllosilicate group. First described in 1788 and named in honor of Colonel Hendrik von Prehn, it is commonly found alongside calcite and epidote within basaltic geological settings. Its characteristic crystal forms—prismatic, tabular, and botryoidal—offer revealing perspectives on its mineralogical development. Renowned for its vitreous sheen and subtle green tones, Prehnite has long been esteemed for use in finely crafted beads, cabochons, and detailed carvings. This specimen from Imilchil, Morocco, exemplifies these refined qualities.
