Synonyms: Green Peacock, Verde Pavao
Location: Peacock Green granite is quarried at quarry RN 000157 and RN 000222, Corrego do Estevao, Vila Pavao, Espirito Santo, Brazil. It is also available in a much lighter shade called Peacock Green Light.
Description: Peacock Green granite is a coarse to very coarse-grained, dark grey-green charnockite. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a charnockite.
The veining and colour varies and a small sample of Peacock Green 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, Peacock Green granite is frost free and polish constant.

Charnockite: A hypersthene granite typical of Precambrian assemblages that contain migmatites. Charnockite is composed of orthoclase, oligoclase, quartz, and hypersthene; it also often includes the garnets almandine and pyrope, as well as biotite, magnetite, and other minerals. Two types of charnockites are distinguished: ferrohypersthene charnockite and garnet charnockite.
