Granite is not just any material; it is a natural stone. Other hard rocks, such as gabbros, syenite, gneiss etc. are also popularly, yet erroneously, referred to as granite. ‘Granite’ has therefore become a generic term and one that we too, have used in this catalogue for simplicity. However, all these types of rock have one thing in common: they are the hardest, most stable and most durable of all natural products.
