A bed of tightly-packed crystals is a common growth habit particular to quartz and amethyst, where the crystals grow up from a matrix and only one termination pyramid is present. When the bed has a very fine crystalline structure similar to sugar or salt crystals, it is known as "Druzes", "Druzy", "Drusies" or "Druzi" quartz which has an "encrustation" crystal habit. This aggregate of minute crystals coating a surface is also referred to as "druzy encrustation.". In it's natural state, druzy quartz is clear, white, tan, golden (citrine), and light purple (amethyst). Druzy crystal is typically cut into flat planes (calibrated) to be placed into a jewelry setting.
