Granite
Granite is a natural stone formed from liquid magma, the molten rock found at the core of the planet, cooled slowly to form a substance approaching the hardness and durability of a diamond. While granites differ in colour, texture and crystalline structure, all granites have three essential minerals in common: Feldspar (50% +), Quartz (25 – 40%), and Mica (3 – 10%). Different proportions of these minerals allow granites to vary in colour, texture, and structural characteristics.
