A coarse-grained gneiss composed mainly of hornblende (black), plagioclase (white), and garnets (red).
Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying composition, while other bands contain granular minerals with an interlocking texture. Other bands contain platy or elongate minerals with evidence of preferred orientation. It is this banded appearance and texture - rather than composition - that define a gneiss. Although gneiss is not defined by its composition, most specimens have bands of feldspar and quartz grains in an interlocking texture. (http://geology.com)
Garnet often forms in Gneiss as you see in these stones, which make for really nice stones. Leave natural or Raw as you see here, or cut/polish these pieces for unique pieces.
The garnets are the small red/orange colored spots seen in the photos.
