Before you make a purchase, please understand that marble blocks are products of nature and natural fractures are common but not defects. Marble reaching the market come from mountains that are many years of age and any inherent fractures and crack lines are a part of the natural character of the stone.
Marble is a product of nature and no two pieces are exactly alike. As a natural product they are prone to variations in color, flow, grain, tonality, veining, shade and texture. Natural fractures and crack lines existing in your stone are intrinsic, which actually adds to the beauty, history and charm of the material.
Fractures and natural crack lines are sometimes treated with liquid epoxy, but only when artisans consider it absolutely necessary, wherever possible, such fractures and crack lines are left in their natural state for its beauty.
