Chalcedony is a collection of quartz with a cryptocrystalline structure composed of regular silicon dioxide. The real gem is conventional with a beautiful design, meaning it is well transformed into a plane gemstone. Most of the part of chalcedony stone is cloudy or sometimes clear because of its crystal structure. The name Chalcedony came from the Latin word chalcēdōnius; its pure structure is likewise alluded to as Sard or Carnelian. The name Chalcedony traces back to Byzantine times and is believed to be named after the city Chalcedon, presently called Kadikoy and essential for Turkey.
