Nero Portoro translates to Black Portoro.
You are probably more familiar with marble than you realize. From Michelangelo's mighty carrara marble David, to the intricately carved cenotaphs of the Taj Mahal, to the royal Marble Arch of Buckingham Palace, marble has been the stuff of civilized architecture and art for centuries. Being a form of limestone, it is softer than granite, making it more susceptible to deterioration and wear but a simple, regular maintenance routine will keep marble looking beautiful.
Marble has a soft, sophisticated aura. Small interior spaces will especially benefit from marble's less "busy" feel when compared to granite thanks to its large, flowing veins.
Certain marbles can be “book matched,” meaning the edges of two panels are paired to create a mirror image. Book matching's effect is best expressed on large panels.
