Peacock crystals, primarily Bornite and tarnished Chalcopyrite, are believed to promote happiness, joy, and emotional healing by assisting in the acceptance of one's situation and channeling positive energy. Metaphysically, these stones are used to align the chakras, promote creativity and artistic vision, and encourage communication and self-expression. While the concept of "peacock crystal" is primarily rooted in metaphysical beliefs, the iridescent colors of the mineral have been a source of wonder and inspiration for centuries.
