granite
as the hardest structural stone, natural granite makes an ideal choice for flooring, counter tops and vanities, as well as finding use in exterior applications. its many stylish patterns and colours make it the most versatile and popular of all decorative stones. characterised by great stiffness and density, its wonderful patterns have been created by minerals melting into its once liquid mass. granite is one of the most common examples of igneous rock, providing and extremely hard but uniquely attractive work surface.

marble
the enduring beauty of marble has been appreciated throughout the millennia, its name coming from the greek for “gleam”. some mediterranean quarries have been producing marble ever since. marble is a metamorphic rock swirled or clouded with colour, but calcite and dolomite marbles, for example, are pure white. Its unique texture derives from the size and uniformity of the grains within it, its special colours due to the various elements and compounds it contains.
sandstone
sandstone is a type of rock made from sediment — the sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. it is composed mostly of sand particles, which are of a medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. more precisely, sand is between 1/16 millimeter and 2 mm in size, silt is finer and grain is coarser. the sand grains that make up sandstone are aptly referred to as framework grains. sandstone may include finer and coarser material and still be called sandstone, but if it includes more than 30 percent grains of gravel, cobble or boulder size it's classified instead as conglomerate or breccia (together these are called rudites).
