Mexican Noce Vein Cut is quarried near Torreon, Mexico. This is a sedimentary stone that is formed in hot springs and is composed of calcite calcium carbonate and has long voids made from bubbles of decaying plants and animals millions of years ago. In order to acheive this linear look, the stone blocks are cut vertically, which is the traditional way of producing travertine. During the polishing process, a polyester resin is applied to the surface of the stone to fill in any natural pits, cracks or fissures that may exist. It is possible for some of the more minute pits that are too small to effectively hold the resin, to reopen during other finishing stages. The resin-filled areas do not polish and therefore may appear dull in comparison to the rest of the slab. However, this does not affect the durability, maintenance or beauty of the stone. There will be noticeable variations in color and movement between pieces. Therefore, it is important and recommended that a range of this product be viewed before finalizing a purchase. As a natural stone product it is recommended that it be sealed to extend its longevity
