luster. Luster refers to how light is reflected off the surface of a mineral or rock, which can help in identifying its characteristics and composition.
Scoria rock generally has a dull to glassy luster. It can appear shiny if it has a vesicular texture with many cavities reflecting light, but overall its luster is not as shiny as some other volcanic rocks like obsidian.
Breccia usually has a dull to earthy luster due to its composition of angular rock fragments and matrix. The luster of breccia can vary depending on the types of rocks it contains and the amount of matrix present.
The luster of sedimentary rocks can vary depending on their mineral composition. Some sedimentary rocks have a dull or earthy luster due to their clay or silt content, while others may have a vitreous or pearly luster from quartz or calcite crystals. Overall, sedimentary rocks tend to have less of a metallic or glassy luster compared to igneous or metamorphic rocks.
It's not exactly that rocks don't have luster/can't be shiny, but luster is a characteristic that we typically apply to minerals to help categorize and describe them. Rocks are made up of minerals so you may be able to spot some of the luster within a rock depending on the minerals it is made of.

Only minerals have lustre, not rocks.
i think that igneous and metamorphic rocks uses luster because maybe they have it in them
