Synonyms: Golden Persia, Persa Gold, possibly Juparana Persa
Location: Golden Persa granite is quarried at .
Description: Golden Persa granite is a fine to coarse-grained pearl white to brown-yellow granite (partly grading to pegmatite with areas of graphic granite) of the Precambrian period. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a granite.
The veining and colour varies considerably and a small sample of Golden Persa 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, Golden Persa 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.
