Based on the following physical properties, what mineral is being described?
This mineral has a hardness of approximately 7, a prismatic crystal, no cleavage planes (fracture), can be many different colors, and if one of the most common minerals on the surface of the Earth.
This mineral is approximately a 6 in hardness, has 2 distinct cleavage planes at 90 degrees, and is differentiated from orthoclase (or potassium feldspar) because of the striations on its cleavage surfaces.
This mineral has a hardness of 3 and as a result powders on the surface of a penny. It has a rhombic crystal shape, 3 planes of cleavage at 60/120 degrees, and shows the curious characteristic of double refraction.
