Explanation

Something with luster has a certain kind of sheen or shininess, like the way a new pair of shoes looks right before you step into a pile of mud. Luster is a noun that commonly refers to a soft sheen, glossy surface, or brightness. It comes from the Italian word lustro, which means "to make bright." Daniel Defoe, author of the novel Robinson Crusoe, once famously said, “The soul is placed in the body like a rough diamond, and must be polished, or the luster of it will never appear.”
