Patterns and colors may vary from stone to stone.

Calcite is a chemical mineral that forms a large family with many colors. Calcite forms in deposits on the mud bottom of an ocean or a salt lake. These deposits are mainly made up of liquid calcium, shells, algae debris. They will gradually solidify during diagenesis (transformation of sediments into sedimentary rock). The resulting rock is mainly limestone and calcite minerals.

Like many stones in the carbonate family, calcite stone comes in various colors. Indeed, it exists in yellow (or honey), orange, green or blue. It has various inclusions such as iron, zinc, copper, lead, manganese, aluminum, nickel, etc. The shades of this stone vary depending on these inclusions, the presence of various trace elements or different minerals.

Blue calcite is mainly composed of natural calcium carbonate. Carbon and manganese can also be found. Blue calcite is opaque. In addition, its color can vary from a very light blue to a darker blue or turning gray, more or less bright. Calcite stones can contain white streaks or other blue bands. Very widespread on earth, calcite is formed, like marble, in metamorphic rocks and in limestone rocks.

There are no legends or myths related to calcite, regardless of its color. Calcite is a name coming from the Latin "khalx", meaning lime. Mineralogy experts have found traces of blue calcite since antiquity. During archaeological excavations in Egypt, many objects were discovered in calcite of various colors. Then, the stone was often confused, or even renamed "calcareous spar", "androdamas", "drewite" or "aphrite".
Thus, in the 17th century, many researchers fell under the spell of calcite and its property of birefringence, a physical property that allows light to be diffused into two distinct light rays. Thus, in 1669, the Dane Rasmus Bartholin was seduced by a colorless variety "Iceland spar".
Many studies were then carried out on this calcite stone, notably that of Gabriel Delafosse, in 1840, who invented crystallography.
Today, calcite is used in the manufacture of lime, cement and building materials. It is found in many industries, glassmaking, metallurgy, the chemical industry. It is even used in the manufacture of certain fertilizers.

The main deposits are in Mexico, Madagascar, the United States, Canada, etc.
