Marble has a high-perceived value. It is also a unique material in the sense that no two pieces are exactly alike. The patterns, colors, and veins of each piece are unique to that piece. Also, marble is elegant in appearance, and because of its weight, it provides a higher perceived value to whatever product it is used in, such as a pen set or a desk clock. For many consumers, weight is directly related to value.
