Synonyms: Rosa Francesco, Rosa San Francesco, San Francesco
Location: Rosa Nule granite is quarried near Luras, Sassari, Sardegna, Italy.
Description: Rosa Nule granite is a Commercial name for a medium to coarse-grained, grey-pink biotite granite of the Carboniferous 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 Rosa Nule 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, Rosa Nule 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.
