Most feldspar minerals have a specific gravity within the 2.5-2.8 range while their Mohs hardness hovers about 6 to 6.5. In addition to all these similarities in physical properties, all feldspar minerals have a vitreous luster that is mostly pearly on cluster faces. This is a great way of identifying feldspar minerals.
