Clear quartz is known as the Master Healer and can be used for any condition, although it is believed to be a good aid to concentration and decision making so would make a helpful study aid.
Clear Quartz acts as a spiritual energy amplifier raising and strengthening your spiritual connection and attuning you to your spiritual purpose.
It is therefore also a good crystal for holding during meditation.
