Proustite is a striking silver arsenic sulfosalt mineral, typically forming in hydrothermal veins associated with silver deposits. Known as "ruby silver,” it displays a deep, vivid red colour with a brilliant metallic to submetallic lustre, often appearing in prismatic or granular crystals. Folklore celebrates it for attracting wealth and protection. Metaphysically, Proustite is believed to stimulate the heart and mind, enhancing clarity, creativity, and passion. It is also said to aid emotional healing, boost intuition, and strengthen one’s connection to spiritual energy.
