Synonyms: Beta Rosa, Rosabeta, Rosa Betta, Rosa Sardegna Beta, Rosa Sardo B, Rosa Sardo Beta, Rose Beta, Rossa Beta

Location: Rosa Beta granite is quarried near Arzachena, Luogosanto, Tempio Pausania, Sassari, Sardegna, Italy.

Description: Rosa Beta granite is a commercial name for a medium to coarse-grained, grey-pink granite or quartz monzonite of the Carboniferous period. Ideal for both interior and exterior use, Rosa Beta granite is frost free and polish constant. The veining and colour varies little and a small sample is usually representative of the whole slab.

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.

Quartz Monzonite: (Or adamellite) is an intrusive igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Quartz monzonite porphyry is often associated with copper mineralization in the porphyry copper ore deposits. Because of its coloring, it is often confused with granite, but whereas the mass of granite is 20% quartz, quartz monzonite is only 5-20% quartz.
