Spirit Quartz is actually a community within a stone, exhibiting many small formations encrusting its sides. Each of these tiny crystals works (vibrates) in harmony creating a choir of crystal energy! Spirit Quartz is a high vibration stone.
Harmony is the key word to describe Spirit Quartz, as it helps to harmonize the levels of the aura, the chakras, the meridians and the physical body. Quartz brings Spirit into play with all aspects of one's inner and outer life.
A funny side note - "It's name is derived from a similarity of the purple Amethyst color to that of a popular (in South Africa) window cleaning solution named Spirit." Robert Simmons
