Description: A medium to coarse-grained, ochre-yellow to golden-brown, also light pink gneiss (pegmatitic orthogneiss) of the Precambrian period, with biotite and garnet, Italian (giallo=yellow). This stone internationally may be nominated as a granite however in the area of application of the European Standard (EN) this stone must be nominated as gneiss.

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.
