RMS Natural Stone & Ceramics Pty Ltd carries an extensive range of Marble Tiles.   Check our Catalogue Marble is a metamorphic rock, formed when limestone is subjected to enormous forces inside the earth's crust. This process, called re-crystallization, causes changes in texture and composition. Fossilized materials, along with carbonates, form large, coarse grains of calcite. Any impurities present affect the mineral composition and the colour of the marble that forms. Marble is found in many countries and in all corners of the globe.Today, the quarrying and production of marble is a very involved and highly automated process using a variety of purpose-built machines. Nevertheless, the human eye remains the crucial factor when evaluating and classifying the product. Marble has long been valued for its beauty and strength; it was and still is widely used in buildings, monuments and sculptures. Even the ancient Greeks used marble for just this purpose; and who has not heard of Michelangelo, the undisputed master from Carrara who used marble for his statues?!
