I cannot say anything to the characteristic of the pebble tile because the sample sent was 4 pebbles. Really! Four pebbles glued to a board. The sample cost me over $1 a pebble! I am quite flabbergasted. With only 4 pebbles it is hard to tell what the pattern or size range would really be. Also, since they were just glued to a board there was no way to tell of the quality of the backing or edge. Needless to say I will not be purchasing tile from Wayfair. 

Very disappointed!
