Natural Stone Pebble in an easy to install mosaic form. A 12" x 12" sheet that nest together for a natural look. Natural Stone Pebbles can be used for any project inside or outside the home AND can be installed on any floor or wall. The Natural Stone Pebbles are available in three colors in a sliced (flat format) or natural (rounded). All pebbles are hand selected for size and all are rectified to provide a flat floor or wall. Even the rounded Pebbles are cut on the backside so all of them are at the same height.
