Found in copper-rich oxidised zones, it often accompanies other secondary minerals, adding to its visual appeal for collectors. Historically, blue minerals like cornetite were valued for protection and clarity of thought. Metaphysically, cornetite is thought to enhance focus, insight, and spiritual awareness, supporting personal growth and self-expression. A captivating stone for those seeking vibrant energy and serene beauty.
