gold marble slab

Italy Portoro Gold Marble Slabs are natural Italian black-and-gold stone selections originating from the Portovenere and La Spezia area of Liguria. Commercially known as Nero Portoro Marble, the material has a deep black limestone background crossed by irregular golden-yellow and occasional white calcite veins. Esta Stone supplies polished slabs for hotel wall cladding, villa dining tables, bathroom interiors and custom architectural panels. Catalogue thicknesses include 18mm, 20mm and 30mm. The distribution of gold veins varies between slabs, making full-slab photographs, cutting orientation and approved panel layouts essential for coordinated fabrication.
