Isfahan Black Marble

also known as Nero Isfahan, Black Persia, Iran Black Marble, Sangi Siyah Esfahan

A deep charcoal-to-black metamorphic marble from quarries in Isfahan Province, central Iran. Iran has an extraordinarily rich stone geology and Isfahan's black marble is one of its most striking varieties: dense, uniformly dark with a fine grain that takes an exceptional polish. Often compared to Nero Marquina in tone but with a slightly warmer, less pure-black character and occasional grey crystalline veining. Used in luxury hospitality interiors, prestigious flooring and high-contrast architectural features.
