Luster

Real World Example

Imagine you're trying to pick out the perfect pair of sunglasses, but can't decide which style looks best on your face. Just like sunglasses interact with light to enhance or diminish your appearance, a mineral's luster is about how its surface reflects light, affecting its visual appeal. The way sunglasses reflect and alter light to either highlight or mask certain features is similar to how a mineral's surface gleams, determining its luster and aesthetic value.
