it depends on color and gloss, but best to get area rugs and furniture protectors. Also Marble is VERY sensitive to acidics, so do not drop sliced orange on it.

marble is a very soft natural stone,that is easy to scratch and stain...that said,don't worry to much find out if the floor has been "sealed" how often does it need to be done (who installed the tile will recommend a maintaince schedule)...as for scratches other than carpet,what floor doesn't.use common sense , and furiniture rests.....good luck
