Clear Quartz is known as the ‘Master Healer’ as it can focus and amplify the energy of other stones. Clear Quartz can be used in place of other stones in crystal gridding and other activities. This stone can enhance the memory, stimulates the brain and can aid in concentration. Clear Quartz is a great stone to use in meditation, and can help motivate and give greater power to one’s manifestations. As this stone is a natural amplifier, it is not suggested to use with cancer patients.
