|GRANITE is an Igneous rock is formed by volcanic action or intense heat, which liquefies
rock deep in the Earth and which solidifies upon cooling. Granite, the most common igneous
rock, is millions of years old and has a crystalline, granular structure, with a range of colors
and consisting mostly of quartz and feldspars, accompanied by one or more dark minerals
such as mica. The color of igneous rock depends mainly on the color of the prevailing
feldspars. The granite offered for residential and commercial applications comes from open
pit quarries found all over the world. There is a large assortment of granites available to suit
specific tastes or design applications, ranging from consistent grain structures and colors to
multicolored stones with veins or movement resulting from the uneven distribution of
minerals. “Consistency”, when applied to natural stone, is a term of relative value that needs
to be understood in the context of the origins and composition of the product. Because of the
way granite was formed millions of years ago, it is synonymous with quality, strength,
permanence, solidity and hardness. These characteristics make it an ideal choice for a
kitchen countertop surface.
Most granite used for countertops is polished to a high-gloss finish giving it a mirror-like
appearance. On closer inspection however, many granites have certain natural
characteristics such as “pitting”, “fissures” or “dull spots” that may at first cause some
concern. It is important to understand the geological reasons for these characteristics to fully
appreciate the beauty of stone.
A characteristic referred to as “pitting” is normally due to the fact that granite is a natural
product that has a crystalline structure, sometimes resulting in small spaces between the
varying mineral crystals. In some cases, certain tiny crystals may also be removed during the
polishing process, causing the pits to become more visible. Various steps are taken during
the finishing process to reduce the visibility of these pits, but they cannot be totally avoided
in all granite types. Pitting will not become worse with regular use or with the passage of time.
Many types of granite have small “fissures” or hairline cracks on the surface of the slab,
usually more visible in the larger quartz crystals. These surface fissures should not be
confused with structural cracks that permeate the entire slab. Fissures are a natural result of
the heating and cooling of the stone during its formation millions of years ago. Fissures will
not grow or expand over time.
The final appearance of the polished surface of each type of granite is determined by the
specific composition or “mix” of quartz, feldspars and other minerals. While the overall
appearance will be that of a high-gloss finish, some components within the granite may not
accept the same level of polish as the rest of the crystals, which can result in "dull spots" or
"watermarks." Often these spots are visible on the darker crystals present in some granites.
The hardness, composition and any other characteristics are taken into account during the
polishing process and all efforts are made to achieve the highest level of gloss possible for
each specific material.
While the type and specific composition determines the amount of pits, fissures and dull
spots, some granites exhibit these characteristics more than others, and they may also be
more or less visible depending on the lighting conditions present in a room. Lighting plays an
important part in the overall appearance of a finished granite countertop surface.
Pits, fissures and dull spots do not compromise the integrity of the stone in any way; they are
natural characteristics of stone and will not impair the function or durability of the material.
They are an expression of nature and add to the allure of the stone, which sets it apart from
