Verde Gloria Granite
Return to granite samples page.
Location: Verde Gloria granite is quarried at quarry RN 000076, Rodovia BR 330 km 17, EStrada Jequie-Jitauna, Jitauna, Bahia, Brazil.
Description: Verde Gloria granite is a medium green-black charnockite of the Precambrian period with striped veining. 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 Verde Gloria 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, Verde Gloria 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.
