Chalcedony is a gemstone species which belongs to the quartz group of minerals.
Technically, chalcedony is the gemological term applicable for all
varieties of quartz in cryptocrystalline form, which can occur in a wide
range of different colors, sizes and patterns. However today, the term,
'chalcedony', is most often used in reference to a very specific type
of cryptocrystalline quartz, often referred to as 'actual chalcedony' or
'chalcedony in the narrow sense'. To minimize confusion, other
varieties of cryptocrystalline quartz are traded under their own
individual trade names, such as 'banded agate', 'carnelian' or 'jasper'.
The gemstone chalcedony is distinguished by translucency and its solid, lighter color, typically ranging from bluish to white or gray.
