For industrial uses, limestone. For collector specimens, vugs in limestone.
The mineral that commonly forms crystals shaped like a rhombus is calcite. Calcite crystals can exhibit a range of forms, but their rhombohedral cleavage is a distinctive characteristic. This means that when calcite breaks, it tends to create rhombus-shaped fragments. The unique crystal structure and cleavage make calcite an important mineral in geology and various industrial applications.
Calcite is birefractive which means that its refractive index depends on the polarisation and direction of propagation of the light that reaches it. For more introductory information please see the wikipedia article about this substance.
yes its softer
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
reaction to an acid
No, calcite is not magnetic. It is a non-magnetic mineral.
Calcite is an example of a carbonate mineral.
No. Calcite is a carbonate mineral.
how does calcite split

Calcite can form limestone
how does calcite split
Calcite belongs to the calcite group of minerals, a group of related carbonates. Many important chemicals are created from Calcite, as well as useful drugs.
on the mohs scale calcite is 3
No. Calcite is a carbonate mineral.
The streak color of calcite is white.
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
