Is marble man made or natural?
Natural stones such as marble, limestone and granite need to be sealed regularly, and because they’re soft, they scratch easily. The price of solid surface is comparable to the price of many natural stones. Cultured marble is a man-made marble that costs a half or a third less than solid surface.
Why is marble so important?
