Both halite and calcite are white to transparent, but have different Cleavage and crystal shape. Rock salt has cubic cleavage, forming cube-shaped minerals. Calcite has three cleavage directions, but not 90 degrees, so the mineral has a diamond shape. Rock salt also has a salty taste, while calcite does not.

What are two easy ways to differentiate between calcite and halite?

Also, when considering appearance, calcite comes in different colors such as grey, yellow or green, while rock salt usually comes in different colors, e.g. Light blue, dark blue, purple, pink, red, orange, yellow and grey.
