Cracked diamond clean everywhere, in the mineral shows (Hekikai) cleavage very strong, very weak shock, calcite is a stone on the other hand its beauty as Jewelry Beadsshould not be treated almost.
The origin of the name comes from the Latin (lime calcit). Stone has been used as a medicine for a long time, raise the heat of the body.
The components contained, you can also see a variety of color variations. For example, purple and green to light red, and pink, including nickel, and cobalt, including yellow, and contains manganese and ferruginous, he is blue and contains a strontium.
Phenomena such as visible or causing me to dub two "phenomenon (double image) doubling", from the nature of the cleavage that has a strong optical phenomena "birefringence (double refraction)" that, when placed on the character I am a stone often used, such as a science experiment.
Also, take the form of various Clear Crystal Beads , plate-shaped, hexagonal, and needles. I say polymorphs such properties, it is well known that such properties also show aragonite.
Basically, such as large gemstone is likely to yield, in ancient times seems to have been used as a material for building materials and sculpture. Called Iceland spar, with that of calcite calcite optical quality clear and colorless.
I need to be careful because it mainly of calcium carbonate, weak to water, calcite shine so lost for a long time and has been exposed to water.
