Prehnite from Morocco

Prehnite (chemical formula: Ca₂Al(AlSi₃O₁₀)(OH)₂) is a phyllosilicate mineral. It forms tabular, botryoidal, or radiating aggregates in soft apple-green to olive hues. Its translucent texture and greasy luster evoke a serene elegance, earning it the title of "the healer’s stone" in mineral circles.
