Luster: Vitreous to resinous to dull in massive forms
Transparency: Transparent to translucent
Crystal System: Trigonal; bar 3 2/m
Crystal Habits: Extremely variable with almost any trigonal form possible. Common among calcite crystals are the scalenohedron, rhombohedron, hexagonal prism, and pinacoid. Combinations of these and over three hundred other forms can make a multitude of crystal shapes, but always trigonal or pseudo-hexagonal.
Cleavage: Perfect in three directions, forming rhombohedrons
Specific Gravity: 2.7
Associated Minerals: Fluorite, quartz, barite, sphalerite, galena, celestite, sulfur, gold, copper, emerald, apatite, biotite, zeolites, several metal sulfides, other carbonates and borates and many other minerals.
Best Field Indicators: Crystal habit, reaction to acid, abundance, hardness, double refraction and especially cleavage.
