Druzy Quartz (also spelt as Drusy or Druse) is a thin layer of quartz crystals covering the surface of a host stone. One good example of Druzy is the crystals filled inside the cavity of a geode. It is well known that amethyst or citrine get the source of their color from this quartz crystal but usually Druzy Quartz takes the host stone`s color which is seen through it as in chrysocolla or uvarovite garnet. The term "Druzy" refers to the tiny crystal which is formed within of on another stone in a large number. When the ground water that carries dissolved silica is forced to to get filled into a porous area of rock, rapid cooling occurs and it causes the formation of minute crystals. As in Druzy Chrysocolla
