Caribbean Calcite is a stone of spirtual awakening, transformation and emotional understanding.  Its calm blue reminds us of the peace and harmony of the ocean.  It is a healing crystal with soothing energies that calms anxiety and tension.  It's like a cool breeze on a warm day.
The Tower is a generator, concentrating its energy in one specific direction, setting and manifesting intentions.  Wherever towers are placed, they emit and focus their energies in intense energy flow.
