Oro Fino Granite
Return to granite samples page.
Synonyms: Fine Gold
Location: Oro Fino granite is quarried in Brazil.
Description: Oro Fino granite is a coarse-grained, yellow/gold granite of the Precambrian period with white-grey quartz and brown veining. This stone internationally may be nominated as a granite but in the area of application of the European Standard we are awaiting clarification.
The veining and colour varies considerably and a small sample of Oro Fino 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, Oro Fino 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.
Gneiss: A common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. Gneissic rocks are usually medium to coarse-foliated and largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, etc.
