Each rock (whether it is a crystal or not) has a higher or lower density vibration. This makes certain rocks (crystals & stones) powerful collectors of Magick energy.
Whenever you are in a situation where you are about to buy stones or crystals, it is important to physically touch different ones before buying them. It helps to close your eyes and really "feel" the stone - concentrate on how the stone resonates with you, and select the ones that are special.
