Commercial classification sometimes differs to the scientific, geological designation. In particular, some limestones are deemed marble especially if they take a high polish. Read more here.
|Age||900 Million years (Pre-Cambrian)|

MOHS is the standard scale of hardness for minerals 1-10, with 10 being the MOHS of diamond. We also use the broad terms Hard and Soft for simplicity. Read more here.
Two Balmoral types are quarried in the area of Taivassolo-Vehmaa, which only differ in the grain size, Balmoral coarse and Balmoral fine.
Petrology:A separated, evenly distributed medium to coarse-grained crystal structure. Up to 2cm intense red orthoclase feldspars determine the shade. Consisting of about 15% quartz, the 3-5mm grey-brown crystals make little visual impact. By contrast, the black biotite mica (10-15%) accentuates the homogeneous granular structure.
Petrogenesis:Several granite melts of different composition entered the lower earth crust in the southern Scandinavian area during primeval times of the earth and crystallised over millions of years to medium to coarse hard rocks. Their main components are feldspar, quartz and mica.
