Coral Reef Granite
Return to granite samples page.
Location: Coral Reef granite is quarried in Brazil, the availability is said to be low.
Description: Coral Reef granite is a medium-grained, beige granite from Brazil with shades of pink and brown with strking vein patterns. This stone internationally may be nominated as a granite however in the area of application of the European Standard we are awaiting clarification.
The veining and colour varies considerably and a small sample of Coral Reef granite may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Coral Reef granite is frost free and polish constant.

Granite: Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark grey or even black, depending on their chemistry and mineralogy.
