Opal White is quarried from a bedrock quarry about 135 miles from Hanoi, Vietnam. This white marble has a consistent structure and the slab sizes are large. Because this is a very pure calcite it can be back lit like onyx. Opal White has an elegant, clean look which lends itself to the modern contemporary kitchen. Although white marble can scratch, etch or stain, because it is a softer product, if you are willing to keep it sealed and understand the recommended maintenance, it will be a beautiful addition to your home. As a natural stone product it is recommended that it be sealed to extend its longevity.
