The chromatic beauty of Verde Alpi marble
A general and anonymous name for a prestigious, elegant marble which is easily recognizable among the wide range of green stones.
Valle d’Aosta, in the western Alps
It has a dark green background tone which may appear uniform at first sight but in reality it has a lot of light and dark shades and white and yellowish veins which characterize and distinguish it.
Weight per unit volume:
It is suitable for products intended for interior and exterior locations, for floors and coverings. It is a strong material, it withstands the cold but in the humid and rainy areas, with rigid temperatures reaching down several degrees below zero, it can be damaged. The water, penetrating gradually in the small cracks, can freeze and expand itself creating breaks.

The green stones represent shreds of oceanic crust emerged after the collision between Africa and Europe caused by movements of the tectonic plates.
They are magmatic serpentine rocks with a breccia structure which have undergone to metamorphism process or rather solidification of the magmas and of the serpentine clasts with chemical deposition of white calcite from circulating waters rich in bicarbonates of calcium. They distinguish themselves in basic (with a silica content between 45% and 52%) and ultrabasic such as serpentine, ophicalcites, eclogite (with a silica content lower than 45%).
They constitute a particular example of green ophicalcite of the Valle d’Aosta region with their typical dark green color with white veins, including Verde Aver, Verde Issorie, Verde Saint Denis and Verde Issogne.
The perfect polishing, which can be achieved thanks to their high hardness, exalts the chromatic contrast between the green of the serpentine and the white of the calcite in order to make them a refined material thanks to their unique decorative beauty.
They are considered prestigious ornamental rocks for coverings of great visual impact.

In the next articles we will talk about Porphyry which is a suggested material for exterior mountain locations because it withstands to snow, rain and ice.
The information contained in this article are for guidance only. We remind you that a lot of marbles are mentioned with the well-known commercial name, often different from the real one.
