Black Pearl is quarried from a bedrock quarry in Andhra Pradesh, India. This granite will have a fairly consistent grain structure between blocks, but some of the slabs will have larger crystals that are more apparent in the material as opposed to others. Black Pearl is quarried in large blocks, consistently providing slabs of considerable size with little to no variation, making this granite perfect for large projects as well as kitchen countertops. There will be noticeable variations in color and movement between pieces. Therefore, it is important and recommended that a range of this product be viewed before finalizing a purchase. As a natural stone product, it is recommended that it be sealed to extend its longevity.
