  According to Britannia.com, agate is is a 'semiprecious silica mineral' and is a type of quartz.  

  It can be found across the globe in areas with ancient lava which has settled in a cavity. 

  The hard outer layer of rock is then penetrated by liquid, often silica which makes its way inside the existing rock and solidifies in different layers. 

  These layers are what provides the interesting patterns within the agate. 

  The stones have been uses as ornaments going back to the time of the Ancient Greek.
