Location: Verde Marina granite is quarried in the Kuppam region, Eastern Ghats, Andhra Pradesh, Western and Eastern Ghats, India.
Description: Verde Marina granite is a fine-grained, grey-green gneiss of the Precambrian period with white and white-grey streaks. 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 gneiss.
Ideal for both interior and exterior use, Verde Marina granite is frost free and polish constant. There are several quarries of Verde Marina granite therefore for large projects and matching ensure all the raw material comes from the same quarry.

Gneiss: A high grade metamorphic rock. This means that gneiss has been subjected to more heat and pressure than schist. Gneiss is coarser than schist and has distinct banding. This banding has alternating layers that are composed of different minerals. The minerals that compose gneiss are the same as granite. Feldspar is the most important mineral that makes up gneiss along with mica and quartz. Gneiss can be formed from a sedimentary rock such as sandstone or shale, or it can be formed from the metamorphism of the igneouse rock grantite. Gneiss can be used by man as paving and building stone.
