How is calcite collected?
Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide.

What would be the easiest way to identify calcite?
Identifying calcite is relatively easy. Firstly, it is generally light-coloured (mostly white) and is translucent to transparent. It’s hardness is about a 3 on the Moh’s hardness scale, so it can’t be scratched by your fingernail, but scratching it with a metal nail or your hammer will leave a mark.
Is calcite a gemstone?
Calcite is a gemstone quality, transparent to translucent variety of calcium carbonate. As a result of the wide variety of colors that calcite occurs in, there are quite a few gemstones that can be confused with calcite, including gypsum, quartz, aragonite and dolomite.
Is calcite a crystal?
This clear rhombahedral crystal is calcium carbonate, a compound of calcium and carbon. It exists in three different mineral forms known as aragonite, vaterite and calcite. The most stable of the three is calcite, and that is the form of this crystal.
Where should calcite be placed in the house?
Place Blue Calcite in any other space you spend a lot of time with your family; in your kitchen, dining room, or living room. The crystal is also a useful home decor element for your office or home office. It helps in decision making, strengthens the memory.
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.
