Biotite granite is a coarse grained igneous rock, usually consisting of quartz, feldspar and micas. In this case, the rock specimen consists of quartz, plagioclase feldspar and some biotite mica. These particular specimens are usually poor in their natural form, so instead have been cut and polished on one surface, thus allowing you to easily view the crystals with your naked eye. The specimens come from Spain and are available in 3 sizes, each piece will be supplied in a card tray with an information label.
