I have this little set myself and use it in rituals on the altars I create for workshops and events aswell as in shrine set ups. This Compass Set  includes 4 free standing pieces of Quartz which have the 4 Compass directions engraved on them (North, South, West, East).
Natural quartz is a very versatile crystal and can do a variety of jobs, from clearing, protecting and strengthening your energy field to carrying any specific quality of energy. 
This Esoteric Pouch Set could be a wonderful addition to your crystal collection!
