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.
Currently the primary method of CZ synthesis employed by producers of
remains to be through the skull-melting method. This method was patented
by Josep F. Wenckus and coworkers (1997). This is largely due to the
process allowing for temperatures of over 3000 degrees to be achieved,
lack of contact between crucible and material as well as the freedom to
choose any gas atmosphere. Primary downsides to this method include the
inability to predict the size of the crystals produced and it is
impossible to control the crystallization process through temperature
changes
