Location: Verde Mergozzo granite is quarried near Mergozzo, Baveno, Provincia di Verbano-Cusio-Ossola, Piemonte, Italy.
Description: Verde Mergozzo granite is a medium-grained, green-white speckled granite or monzonite of the Permian period. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a granite.
A small sample of Verde Mergozzo granite is usually representative not having a wide variation in colour and veining however swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Verde Mergozzo granite is frost free and polish constant.

Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
Monzonite: An intermediate igneous intrusive rock composed of approximately equal amounts of sodic to intermediate plagioclase and orthoclase feldspars with minor amounts of hornblende, biotite and other minerals. Quartz a minor constituent or is absent; with greater than 10% quartz the rock is termed a quartz monzonite. If the rock has more orthoclase or potassium feldspar it grades into a syenite. With an increase of calcic plagioclase and mafic minerals the rock type becomes a diorite.
