 GRANITE
Granite is a compact, polishable rock with visible crystals,
for decoration and/or building
purpose. It is primarily made of Quartz (35%), Feldspar
(45%) and Potassium. It contains very little calcite, if any. Granite provides a
heavy crystalline and granular appearance with mineral grains that usually set
in darker colors. It is a hard material and easier to maintain than marble. This
type of stone comes in a variety of colors ranging from salt and pepper to
reddish brown to jet-black. Granite has a very high density and low absorption.
These qualities make it highly desirable for exterior walls and high traffic
flooring in commercial projects. The low maintenance attribute of granite makes
it one of the most frequently used materials for residential countertops. |

MARBLE
Marble is a stone to which we
generally ascribe an essence of richness, luxury and eternity. It is a limestone
rock, which is to say it contains at least 50% limestone carbonates that
generally crystallize in the form of calcite or aragonite. So marble is a
limestone which has been recrystallized. Marble ranges in many colors and is
usually heavily veined and shows lots of grains. The brilliant colors and
various crystal formations developed when different mineral properties blended
together along with the integration of temperature and pressure. The veins and
color grains of marble were liquid minerals that flowed through the stone when
the Earth heated up.
