Cream Violet Granite
Return to granite samples page.
Location: Cream Violet granite is quarried near Nova Venecia, Espirito Santo, Brazil.
Description: Cream Violet granite is a coarse-grained, yellow-grey gneiss with brown-red garnets. 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 gneiss.
A small sample of Cream Violet granite is usually representative not having a wide variation in colour and veining however 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, Cream Violet granite is frost free and polish constant.

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.
