A mineral with a silky luster often exhibits a soft, smooth appearance reminiscent of silk fabric. This luster is typically seen in minerals like talc, which has a pearly to silky sheen due to its layered structure. The silky luster results from the way light interacts with the mineral's surface, creating a soft glow rather than a reflective shine. Such features make these minerals visually distinctive and can aid in their identification.
