Portoro Extra is a luxurious and highly sought-after black marble that originates from the Ligurian coast in northwestern Italy. This exquisite stone has a rich history dating back to ancient times and has been used in various construction projects throughout the centuries.
The name "Portoro" is derived from the Italian word "porta d'oro," which means "golden door." This name perfectly describes the stone's unique appearance, as it features striking golden veins that contrast beautifully against its deep black background. These golden veins are the result of mineral impurities, primarily iron oxide, that were present during the formation of the marble.
The geological formation of Portoro Extra dates back to the Jurassic period, approximately 190 million years ago. It was formed through the metamorphism of limestone, which occurred under intense heat and pressure. Over time, the limestone transformed into marble, resulting in the stunning black and gold patterns that are characteristic of Portoro Extra.
The Ligurian coast, particularly the region around the town of Portovenere, is the primary source of Portoro Extra. This area has been renowned for its marble quarries since ancient times, and the stone has been used in various architectural and artistic projects throughout history. The Romans, in particular, were known to appreciate the beauty of Portoro Extra and used it extensively in their buildings and sculptures.
