Studio Vertu We are proud to feature Studio Vertu’s Italian Marble Coasters and Tiles. These functional works of art are popular in 13 countries, and a single look at the incredible designs will demonstrate why. Images licensed from The Vatican Library Collection, Guy Buffet and Deborah Schenck provide an amazing variety to choose from.   Images are directly printed on tumbled Botticino marble or on their own Fresco Tile™ made of rigid urethane. The marble is available as a 4-inch or 8-inch tile. The 4-inch marble can be backed with cork and used as a coaster. The 8-inch marble is backed with masonite and is suitable for hanging or table top display in a metal easel.
