The 150mm cobalt blue crystal silica Orb radiates a very strong field of energy that is perfect for a larger home or office. Dominus Cervix lead-free crystal silica Orbs emit an energetic field, causing everything within that field to vibrate at a higher resonance. The energy that emanates from the orbs does not dissipate over time and provides a continuous harmonious resonant field wherever they reside. Within seconds of touching a Dominus Cervix orb of any size, negative energy is dissolved and transformed.
