Apophyllite
Apophyllite is calming and tranquil, and encourages honesty to self and others. It is excellent in stressful situations, and for clearing negative thought patterns. It creates a conscious connection between the physical and the spiritual, and it acts as an excellent transmitter for vibrational energy, and so enhances healing work. When placed in a room, an apophyllite cluster makes an excellent space clearer.
A single natural pyramid of apophyllite can energetically clear a room. It is a wonderful transmitter of energy, and enhances vision and healing work - so much so that many Reiki practitioners refer to it as the "Reiki Stone".
