What minerals make up gneiss?
feldspars, quartz, and mica
What is the streak color gneiss?
Bearing in mind that Gneiss is not a mineral, and that it is very hard, Gneiss does not leave a streak, but scratches the plate (don't try it - this is not how you classify Gneiss). Gneiss is classified by its Gneissose Banding - distinct bands of light Feldspar/Quartz and dark Micas. It is also classified by the extent of metamorphism which has taken place.
Is gneiss smooth and shiny?
Gneiss is a foliated metamorphic rock, displaying bands of light and dark minerals.
What is gneiss luster?
You would need to look at the individual minerals. A rock does not have a luster.

What is the rock gneiss?
The word "granite" comes from the Latin "granum", meaning "grain" in reference to its course granular structure. Granite is normally a light-coloured igneous rock with grains large enough to be visible with the naked eye. It is formed by the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with smaller amounts of mica, amphiboles and other minerals found in the area of its origin.
Does gneiss have minerals in it?
Yes. All rocks, apart from coal and some glassy volcanic rocks, contain minerals.
