Here's a preview from my upcoming book about Crystal Configurations and their energies:

SOULMATE CRYSTALS:  The soul mate crystal can be recognized as two individual crystals of approximate length and size growing side by side. This configuration SYMBOLIZES AND ENHANCES THE REUNITING OF COMPATIBILITY BETWEEN ENERGIES. While a Soul-Mate is generally defined as another being lovingly connected to you at the soul level who will facilitate and promote your spiritual growth, a soul mate can also represent the connection to all of the soul aspects of the self. Whether used as a tool to FOCUS ON CONNECTING WITH ANOTHER INDIVIDUAL OR FOR CONNECTION WITH THE HIGHER ASPECTS OF THE SELF, the Soul Mate Crystal will ASSIST ONE IN DEALING WITH THE FEAR OF INVOLVEMENT AND RELATIONSHIPS IN ANY FORM.
