Also, please take a look at our Luminere Glass Collection. The Riva Del Mar Glass Pebbles Collections is a Marble Systems product offering. The color range allows for a high degree of design flexibility around the material. Always helpful, our partners in knowledge at Wikipedia give us a basic definition that will allow us to understand modern mosaics: “A mosaic is a piece of art or image made from the assemblage of small pieces of colored glass, stone, or other materials. It is often used in decorative art or as interior decoration”. The warmth of the pebble shape works nicely with the cooler feel that the glass elements bring into play.
