This captivating gemstone, a pseudomorph of quartz after crocidolite, displays a vibrant chatoyancy, often described as a “cat’s eye” effect, due to the parallel intergrowth of quartz crystals and altered amphibole fibers. The distinctive blue color results from the presence of crocidolite, a fibrous form of riebeckite, a sodium-rich amphibole mineral. This unique combination of mineral structure and chemical composition creates the shimmering, silky luster characteristic of this stone.
Historically prized for its perceived protective and calming qualities, this mineral is believed by some to enhance communication, self-expression, and intuition. It is often associated with the throat chakra and thought to aid in clear thinking and decision-making. Whether valued for its aesthetic beauty or metaphysical attributes, this striking stone continues to hold significance across diverse cultures.
