Quartz crystals are quite hard, around 7 on the Mohs scale, just under diamond which, along with concerns such as silicate dust makes these crystals challenging to cut. Most quartz crystals are small in size with pyramidal ends. Often one end is broken off from a cluster leaving ragged edges and in order to use the crystals in jewelry those edges need to be cut.
