University of Minnesota's Mineral Pages: Fluorite

Fluorite that forms from higher temperature fluids tends to occur as octahedral crystals, while fluorite that forms from lower temperature fluids tends to occur as cubic crystals. Pure fluorite crystals are clear, so the many colors fluorite crystals come in simply reflect a variety of minor impurities in the crystal's chemical composition that tint the crystal.

University of Minnesota's Mineral Pages: Potassium Feldspar

Orthoclase is the most common potassium feldspar, forming the majority of potassium feldspar found in felsic plutonic igneous rocks, some high temperature veins, and higher-grade metamorphic rocks. Sanidine has a less ordered crystal structure than orthoclase and is primarily found in volcanic igneous rocks where magmas cooled more rapidly and crystals had less time to form.

Mohs Hardness Scale - Rockroost

The scale is not a linear one, and is somewhat arbitrary. For example, Fluorite at four is not twice as hard as Gypsum at two; nor is the difference between Calcite and Fluorite similar to the difference between Corundum and Diamond. Hardness is used in a rough way to inform mineral identification in the field.
