Purchase Crystal Quartz Pencil Points today from Anam Agate. Quartz crystal is a power stone that`s prized as a healing stone. It is known as the most powerful healing stone of the mineral kingdom, able to work on any condition. It has been called the "Universal Crystal" because of its many uses and is beneficial for manifesting, healing, meditation, protection and channeling. Quartz is more valuable when it is completely intact; however, a piece of naturally occurring quartz of unusual color is still worth more and of higher quality than a smooth piece of manufactured plastic or glass designed to imitate quartz.
