Opal has been a popular gem for many centuries and has a very interesting structure.  The name opal comes from the Sanskrit name for precious stone upala.  Opal structure is not crystalline and considered a mineraloid.  The chemistry of Opal is primarily SiO2 and varying amounts of water.  The amount of water varies from 5 -10% and greater.  This water can help geologists determine the temperature of the host rock at the time the opal formed.
