Granite Characteristics

Quarry-photoGranite is used for kitchen and bathroom countertops because of its beauty and durability.

Where does granite come from?
Millions of years ago, deep underground, volcanic action melted rock into liquid magma. The magma cooled and solidified, and the result is called igneous rock. Granite is one type of igneous rock. Granite’s crystal structure comes from quartz and feldspars. There are many ranges of colors of granite depending primarily on the feldspars. It may also contain mica or other dark minerals. Granite comes in a variety of patterns from similar grain to multicolored stone with veins or various shades depending on how the minerals are distributed. All of this is what makes granite strong, durable and unique.

Granite is almost always polished to a high-gloss finish when used for kitchen or bathroom counter tops. This brings out the unique features of each piece of stone. Depending on where it was mined, granite can include dull spots, fissures or pitting. These add to the stone’s beauty and one of a kind quality.

Granite is made up of a different mixture of quartz, feldspars, and other minerals and that is what gives granite its fine appearance. Sometimes, with a high-gloss finish, some of the crystals in the granite do not polish as shiny as other areas. These areas are known as dull spots or watermarks and can sometimes be seen in the darker areas.

Another characteristic of granite is referred to as pitting. Pitting is what happens when there are small spaces between the different mineral crystals in the stone. Sometimes when granite is being polished, some of the small crystals are removed making the pits easier to see. Different steps are taken while finishing the stone to make the pits less obvious, but they cannot be completely eliminated. Just like freckles or beauty marks on a person, pitting makes each piece differ from slab to slab. Pitting should not worsen over time with normal use and preventative care.

Yet another characteristic of granite are fissures, which were created during the cooling process when different flows of hot liquid magma came together and became a single stone. These fissures have always been a part of a specific piece of granite and will not increase or grow as time goes on.

Depending on the granite you choose, some may have more or less pitting, dull spots or fissures. Remember that each stone is unique and matching bundles of stone at a later date will most likely vary in veining, color or markings. How easily each of these characteristics can be seen also depends on the lighting your room. You may ask to take a sample of stone with you to assure you will be satisfied.

*** Important Information***

None of these characteristics, pits, dull spots, or fissures affects the quality or integrity of the piece of granite. They are naturally caused from millions of years of volcanic heating, cooling and formation. They make the stone unique, add character to each piece of granite, and make it stand out from manmade materials. With the proper care, your investment will pay for itself in creating an updated kitchen or workspace.
