Quartz is an essential to any crystal collection. It is an amplifier, healer, and balancer. Place Quartz next to another crystal to enhance the energies of that crystal (i.e. near Black Tourmaline to amplify protection). Placing Quartz on your chest also helps to balance and unblock chakras.
Wands fit great in your hand and can be used as a meditation companion, a great addition to your altar, or can be used in energy work, massage, and reiki.
