An example of rhombic cleavage would be siderite and rhodochrosite. Remember that this is basically a "partically squashed box." Essentially, the direction of deformation in a rhombohedron occurs in one of the three diagonals that run from one corner of the cube to the other. Calcite is not a particularly fabulous example of a rhombohedron, because it is considered to be cubed.
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.
Cleavage of galena is the tendency of the mineral to break along planes of weakness, resulting in smooth, flat surfaces. Galena exhibits perfect cleavage in three directions at right angles to each other, producing cubic or octahedral shapes. This property is a result of the crystal structure of galena.

Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
The term used to describe the shape of a mineral with three directions of cleavage that intersect at 90 degrees is cubic or isometric cleavage. This means that the mineral can cleave in three directions at right angles to each other, resulting in cubic-shaped fragments.
Calcite is a mineral that is white or colorless and has a hardness of 2.5 and splits with cubic cleavage.

In halite, which is the mineral form of sodium chloride (NaCl), cleavage surfaces meet at angles of 90 degrees. This characteristic cubic cleavage results from the mineral's isometric crystal system, where the internal atomic arrangement allows for easy breakage along specific planes. As a result, halite typically exhibits well-defined cubic crystals with sharp edges and corners.

The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
