Granite Color
Natural stones are available in a beautiful range of colors. Colors in marbles and granites
can range from soft beige and pink to classic black and whites to rich corals, greens and
multi-colors.
Almost any color in the spectrum can found in some granite.
Unlike the repetitive sameness of material produced by machine or assembly line, natural
stone is different in every piece. I can see the same color over and over again and yet
the color and appeal is different everytime.

Culture Marble VS. Granite
Cultured marble is manufactured from fiberglass resin, crushed limestone and color pigments. Granite is a natural stone. Both are found on countertops, walls and other locations in the home, but there are major differences between them.
Both cultured marble and granite are often used for bathroom vanities
· Cost
- Granite is far more expensive to buy and to install than cultured marble. The cost of granite depends not only on finding, cutting and shipping it from its natural location, but also on the rareness of the color and pattern of the stone chosen. Each piece is unique. Installation of granite slabs requires careful measuring, cutting, buffing and grouting. Granite can also be purchased precut into tiles, which are less expensive than buying a large slab.
To produce cultured marble, a mold is built to fit the size and shape desired by the home owner. The resin, powdered stone, coloring and other ingredients are blended and then poured into the mold. After it hardens, it is covered with a clear gelcoat sealant. This process is inexpensive to do, and makes the installation fairly quick and easy.
Durability
- The gelcoat placed on cultured marble gives it a non-porous, stain-resistant surface. It does, however, scratch easily, and scratches can become discolored. Granite is highly resistant to being scraped, chipped or stained, and is almost impossible to scratch or jab with a knife. It is one of the hardest and strongest stones found in nature. Cultured marble often comes with a 3 to 5 year warranty. With proper upkeep, granite is expected to last a lifetime.
Uses
- Granite is often used on kitchen and bathroom countertops, and granite tile can be found on floors and walls. Cultured marble is commonly used in bathtubs, shower bases, walls, vanity tops and commode plates, as well as for planters and decorative accessories. Cultured marble is rarely used for kitchen countertops because it may scratch and chip easily under tough kitchen use.
Upkeep
- Granite is sealed when installed, and may need resealing after several years of use. Cultured marble is given a protective coating as part of the manufacturing process. Because it scratches easily, abrasive cleansers should not be used to clean it.
Patterns and Colors
- Granite comes in many colors and patterns, with the most common being gray with a fairly uniform speckled appearance. Patterns with swirls, called "movement," and unusual colors will add to the cost. Granite can be found in shades of gray, brown, pink, coral, green and even blue.
Cultured marble usually comes in neutral colors similar to those found in natural marble. It can also be manufactured to look like granite or slate, and some is made with bold colors. Because many choices are available, it pays to look at a offerings from several manufacturers.

What is so-called "Granite"?
Granite
A common, coarse-grained, light-colored, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica, used in monuments and for building. Granite - Derived from the Italian word, "Granite" meaning "grained." It is a very hard, crystalline, igneous or metamorphic rock primarily composed of dark minerals. Mineral grains are visible to the naked eye. This material is frequently characterized as more resistant to damage (e.g.staining, etching, etc.), harder, and more uniform than marble, travertine, onyx,limestone or slate.A crystalline igneous rock that consists largely of alkali feldspar (typically perthitic microcline or orthoclase), quartz, and plagioclase (commonly calcic albite or oligoclase). Its average grain size is 0.04–1.0 in. (1–25 mm); finer-grained rocks of this composition include rhyolite and aplite, and coarser-grained ones are granite pegmatite.Granite rocks are igneous rocks which were formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Granite is used for long lasting monuments and for trim and decoration on buildings.Material Notes:
Granite is an igneous rock with a mixed texture and grain size > 3 mm (plutonic). It is acidic, with a total silica content greater than 65%. The critical mineral of granite is quartz (5-35%); and also contains orthoclase feldspar, plagioclase feldspar, and smaller amounts of biotite.Granite is used in architecture and construction because it is common and can possess a variety of textures and colors.Granite is a primordial stone with naturally occurring variations in color and pattern. These variations, referred to as 'movement', should be expected and are the source of its natural beauty. Also, keep in mind that the veining in the granite can effect color perception. Sometimes two different grain sizes occurring in the same slab will appear to be of a different color. Mineral concentrations may cause patches that appear darker or lighter.Every slab of granite varies somewhat within any given color and pattern. If you are unfamiliar with granite, a granite slab ordered may not be identical to a sample you are shown. While the samples are intended to represent the quarry's product, each slab may differ slightly in color and veining. Indeed, even a single granite slab will have color variations from one end to the other. This lack of predictability gives the product its unique character and adds an element of nature into human-designed spaces.
