Synonyms: Shivakashy Pink, Siva Pink, Sivakasi Pink
Location: Shivakashi Pink granite is quarried near Tiruttangal, Sivakasi, Tamil Nadu, India.
Description: Shivakashi Pink granite is a pink-grey granulite with reddish bands, veining and 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 granulite.
The veining and colour varies considerably and a small sample of Shivakashi Pink 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, Shivakashi Pink granite is frost free and polish constant.
Mineral Composition: Quartz, feldspar, garnet.

Granulite: Granulites are metamorphic rocks that have experienced high temperatures of metamorphism. They typically have a granular (granoblastic) texture that is, a texture comprised of similarly sized and shaped grains and hence the name granulite.
