Does pumice have luster

Pumice does not have luster because it is an amorphous volcanic glass with a dull and porous texture. Luster refers to the way light interacts with the surface of a mineral, and pumice's highly porous and frothy structure does not allow for the reflection of light in a way that produces a shiny appearance. Instead, pumice is often described as having a matte or dull finish due to its unique composition and physical properties.
