Calcite is a carbonate mineral and is the most stable form of calcium carbonate, one of the most common minerals on earth. With a hardness of only 3 on the Mohs scale, it can only be used in jewelry that won’t be subjected to knocks or scratches , such as earrings and pendants.
What is calcite commonly used for?
The properties of calcite make it one of the most widely used minerals. It is used as a construction material, abrasive, agricultural soil treatment, construction aggregate, pigment, pharmaceutical and more . It has more uses than almost any other mineral.

Is calcite harmful to humans?
IS CALCIUM CARBONATE HAZARDOUS TO HEALTH? Only in concentrated solid form or in very concentrated solutions is calcium carbonate potentially harmful . Direct eye or skin contact with pure crystals or powder can produce irritation. Inhalation of crystals or powder can be irritating to the respiratory tract.
What is the value of calcite?
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. The cost of faceted stone is therefore mostly in the labor of cutting.
Can calcite go in water?
The hardness of a crystal will determine if it is safe to place in water. ... Any crystal from the quartz family is safe to put in water , as are calcite stones.
How do you take care of calcite crystals?
Calcite is barely soluble in water . The influence of temperature on solubility is low. However, if water contains CO 2 , the solubility of calcite increases considerably because of the formation of carbonic acid that will react forming soluble calcium bicarbonate, Ca(HCO 3 ) 2 .
Where is calcite found?
Description: Calcite is an abundant mineral found in many geological environments. It forms by precipitation from ground and surface waters, forming the major component of marls and limestone in the ocean, lakes and rivers .
Can calcite scratch glass?
With a hardness of 3, calcite is softer than glass (5.5), so it does not leave a scratch .
How do you know if a mineral is calcite?
By double refraction when light passes through calcite, it is split into two rays and is refracted twice. I would suggest to take a piece of paper and make a point with pencil, then place the calcite mineral on top of the point and see whether the point splits into two or not. If it does then it is calcite.
How do you cut calcite?
Calcite is most often faceted or carved . The most common shapes and cuts include octagons, ovals and cushions. Fancy shapes, such as trillions and hearts are quite rare, since there is very little demand for jewelry-cut calcite.
Is magnesium in drinking water harmful?
