calcite minerals are trigonal rhombohedral
INDUSTRIAL MINERALS: CALCITE(BLUE)
02.11.2017Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural crystals. However, they show a remarkable variety of habits including acute to obtuse rhombohedra, tabular forms, prisms, or various scalenohedra. Calcite exhibits several twinning types adding to the variety of observed forms.

What mineral has rhombohedral? Explained by FAQ Blog
Calcite is common and abundant throughout the world. The material has little intrinsic value since it is not scarce. However, calcite is one of the most difficult of all minerals to be cut because of perfect cleavage in 3 directions. Therefore, a cut calcite over 50 carats is extremely rare.

What is the easiest way to identify calcite?
Calcite: Shows a rhombohendral crystal shape. Halite has a cubic crystal form, so it cleaves into perfect cubes. It has roughly the same hardness as calcite, and is colorless. Although taste is an important characteristic, caution students to avoid tasting minerals; some minerals have very unpleasant tastes.
