Red-colored granites are fewer in number than green, tan or gold-colored granites. This can make them more highly prized and recognizable to some individuals. To truly appreciate red granite and other red natural stones, it can help to learn some facts about their origin and mineral makeup.
Countries of Origin
The vast majority of red granite is found in quarries in Brazil. The second largest producer of red granite is India, with the United States, Colombia, Saudi Arabia and Australia also producing the stone.
Classification of Red Granite
Many granites are given the classification of "red" that may appear purple, rose, pink or orange in hue. These same stones may also have names such as Amazon Blue or Verde Fouco. This is due to the mineral content of the stone. Stones that contain large quantities of minerals that have a red or pink tone will gain a classification of "red." When a stone is classified as red but has another prominent color, this may be due to the changing mineral content deep within the quarry.
Minerals That Cause Red Granite
Minerals that may be present in any quantity in red granite and other red-colored stones include quartz, feldspar and mica. All three of these minerals may be present, or only one in combination with other minerals to produce a stone's unique color. All three of these minerals can also be present in other colors, occasionally within the same stone, where they appear red.
Common Red Granites
There are not as many red-colored granites as other colors, but there are enough red stones to be easily recognized. These red granites include Violetta, Rojo Guayana, Red Multicolor, Dakota Mahogany and Indian Mahogany. These stones can be found at most granite fabricators and are usually readily available for purchase.
Colors Found Within Red Granites
Some red granites will contain a secondary color that is as prominent as the red hue. Kangaroo or Verde Fouco both contain equal amounts of green mixed with the red. Amazon Blue contains large sections of blue crystals throughout the red base, while any red granite labeled "Bordeaux" will be rose in tone mixed with cream and black.
There are a few granites that are predominantly red with little to no other colors, such as Cinnamon or Red Fire.
