Marble

Meaning

 "Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble may be foliated. In geology the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone"

Kearey, Philip (2001). Dictionary of Geology

Marble has been derived from a Greek word (mármaron). And according to some other people it can be linked to English word marmoreal, meaning "marble like".
