Chalcedony is known to be a mineral derived from silica, of which the chemical formula is: SiO2. It has a microcrystalline structure.

 It was originally seen as a differing from the Quartz, currently it has been shown that it is actually composed of quartz with Moganite, this mineral of the same chemical recipe only monoclinic, thus the usual banded combination for the different chalcedony is produced.

The name of this mineral comes from Calcedonia, a Greek and Byzantine city of the past, located in the Asian region of the territory of the Bosphorus. Currently, you can still find farms of chalcedony in places such as: Brazil, Argentina, Uruguay, Madagascar, India, Namibia, Iceland and Austria.

 This mineral has many features, but one of the primary from the mineralogical point of view is its frame. As mentioned previously, this mineral is linked with quartz, with it it shares the same chemical mixture; Despite this, a mineral as such as chalcedony does not create highly evolved crystals.
