A: Stone is a natural product and cannot be manufactured. Blocks of stone are removed from a quarry, a type of open-pit mine, and from those blocks slabs are cut. The slabs are then fabricated into the final stone to be installed. Natural stone generally comes from all over the world except the United States for countertops. Caledonia , Dakota Mahogany, Virginia Mist are a few granites quarried domestically, among many marbles. Green materials are generally associated with South America, blue hues from the nordic area of the world, and earthtone colors from the middle east. This is a general observation. Each material’s country of origin is readily available from us.
