The Verde Spluga is a gneiss coming from the Spluga valley, in the province of Sondrio (Italy). Location and altitude make the quarring of this material particularly hard. The rock present medium grain and schisting weaving. Its colour is GREEN with the possibility to have some parts containing white quarzite that makes it more shiny. Its features mean that it is ideal for all interior and exterior applications.
