The material extracted from this quarry, with a typology of biocalcerinite of sedimentary origin, is considered to be one of the most resilient, premium-quality sandstones on the market. It is the birthplace of Niwala White, a biochemical non-detritic Lumachelle-type sedimentary rock formed from a high concentration of fossils and shells, fundamentally molluscs and foraminifera that give this stone a life and personality of its own.
