A metamorphic layer is a stone layer comprised of metamorphic rock. Metamorphic layers contain several unique and valuable types of gems; however, they are generally poor in metal ores, lacking any ores of iron. Furthermore the only metamorphic flux layer stone is marble.

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. The protolith may be a sedimentary, igneous, or existing metamorphic rock.
