Often pink or pinkish and can be colorless, white, yellow, gray or even brown or black when iron  present in the crystal.

Luster Pearly to vitreous to dull
Transparency Crystals are transparent to translucent
Crystal System Trigonal; bar 3
Dolomite Crystal Habits

Include saddle shaped rhombohedral twins and simple rhombs some with slightly curved faces, also prismatic, massive, granular and rock forming. Never found in scalenohedrons.

Cleavage Perfect in three directions forming rhombohedrons.
Fracture Conchoidal.
Hardness 3.5-4
Specific Gravity 2.86 (average)
Streak White
Dolomite Characteristics Unlike calcite, effervesces weakly with warm acid or when first powdered with cold HCl.
Associated Minerals Include calcite, sulfide ore minerals, fluorite, barite, quartz and occasionally with gold
Notable Occurrences Many localities throughout the world, but well known from sites in Midwestern quarries of the USA; Ontario, Canada; Switzerland; Pamplona, Spain and in Mexico
Best Field Typical pink color, crystal habit, hardness, slow reaction to acid, density and luster
