Comments

Commercially, the term "marble" includes all polishable decorative calcium-rich rocks as well as some serpentinites, in some cases even polishable granite is called „marble“. Marbles are used for buildings and monuments, decoration, statuary, tabletops and novelties. The most expensive variety, so called „statuary marble“, should be pure white and of uniform grain size.
