Difference between Statuario and Calacatta marble

Statuario marble and Calacatta marble are both types of marble which are from Italy, but they are extracted from different quarries or part of the quarry. Both when cut into slab and polished show a very natural pure white background color, the main difference comes from the veins which for Calacatta marble are thin, intense and light grey & gold colored, instead for Statuario marble veins are of a darker tone and thicker. Most of the times statuario shows one or two/three big thick veins crossing the slabs (those are called ‘’bastoni’’ by Italian marble masters)
