Grey Sardo (Italy)
Granite is signature rock of the planet Earth. Other rocky planets like Mercury, Venus and Mars are covered with basalt, Earth has this attractive and interesting rock. Granite is strong and its strength can be attributed to its acute density acquired during slow cooling of magma. The quartz and feldspar that compose it, are harder than steel. Granite takes good polish and resist weathering very well. This makes Granite desirable for building and ornamental purposes.
The truth is not in the touch of a stone, but in what the stone tells you.
