Natural
Beauty
Unique
and sophisticated are the most appropriate words to
describe the beauty of natural stone. The varieties of
minerals that complete the stone vary in properties and
color, making stone exceptionally beautiful. Flecks of
quartzite, bronzite, garnet, and other materials sparkle
and illuminate the material. Natural stone is completely
distinct, none will have the same pattern, veining, or
defining marks as another, the result will be a truly
unique residential or commercial project.
Three
different types of stone are formed to create the
various types of stone used in homes and commercial
projects today.
Sedimentary
rock
is located on the uppermost part of the crust. It is
formed when an original rock has been destroyed due to
weathering. The sediments are transported by water
(rivers, streams, or ocean) or wind, and then buried.
After the rock was buried, the tiny pieces of sediment
bond to form limestone, sandstone, and travertine.
Metamorphic
rock
is formed when rock that is buried deep in the earth
comes in contact with heat, pressure, and chemically
active fluids. This process results in a more strongly
bonded, dense stone. The heat creates veining that is
present in many stones. Marble, quartzite, and slate are
formed through this metamorphic process.
Igneous
rocks
are found deepest in the earth’s crust; they are
formed by the cooling and solidification of molten
rocks. As the rock cools, crystals form and grow until
the molten rock turns into stone. If the cooling occurs
slowly, large crystals are formed. If the cooling occurs
quickly, smaller crystals are formed. This process is
responsible for producing granite, which is made up of
orthoclase feldspar, quartz, plagioclase feldspar and
ferromagnesium.
The
changes in color result from the minerals involved in
the rock formation. These minerals also determine stone
hardness. On a scale of 1-10 (diamonds being hardest),
granite is a 6-7 and marble is between 3 and 5.
