Granites come from all over the world: India, Egypt, Spain, Brazil, Norway and Africa to name a few. Canada and the United States also produce some very lovely granite as well. Where the stone originates has a high impact on the cost of the stone because of transportation and labor. Red granites and blue granites tend to be priced a bit higher than the other colors because they are more rare.
Granite is an igneous rock formed by volcanic action and consists mainly of quartz, silica, mica obsidian and feldspar with a blend of other natural minerals. The composition varies from quarry to quarry. Granite is the only natural stone suitable for kitchen countertops. This relates to its hardness, resistance to scratches and its minimal absorption. It can also be used for fireplace surrounds and vanity tops. Below are some general physical characteristics, which also vary by stone type.
HARDNESS: Based on the MOH scale of one to ten with diamonds being ten ( 10 ), most granites fall within the range of seven ( 7 ) or eight. ( 8 ) It is extremely scratch resistant.. So, while a careless slip of the knife will scratch most other countertops such as solid surfaces, it won‘t leave a mark on Granite. Although Granite is durable it is not scratch-proof. But close.
NATURAL FISSURES: Granite contains natural fissures, which appear as cracks. These visible hairline cracks are formed during the solidification process. Earthquakes or land movement can also cause fissures. Fissures are random and will vary from one type of granite to the next.
SURFACE PITS: Granite is polished to remove all scratches from the surface. Due to the methods currently used for finishing – abrasives and pressure in a circular motion – some small crystals will be removed leaving small voids in the surface polish. The size and frequency of this varies from stone to stone. Usually, granite with more movement in the stone.
COLOR VARIATION: Samples represent the general color and pattern of a color of granite only. Exact duplication cannot and will not be guaranteed. This is why at Bay Area Stone & Tile we let you pick your own slab! Granite, being a natural product, will have variation in color and shading.
