Calacatta Umber has a clean, white background with darker veins.
This is a metamorphic stone which evolved from a sandstone due to extreme heat and pressure. Over millions of years, water has penetrated deep into this stone through small cracks and fissures, causing the iron oxide and other minerals to oxidize. It is this process that produces the rich, vibrant gold tones that are visible in this stone.
When installing white marble, you must use a white thinset. Using grey thinset will leave trowel lines and could stain the marble. Piece to piece variation in shade or color are inherent in all natural stone products; therefore, when installing natural stone tile, it is recommended to mix tiles from several boxes at a time during installation to achieve the best range of color. As a natural stone product, it is recommended that this be sealed to extend its longevity.
