'The Bridge Quartz Crystal is recognised by a small crystal which penetrates and is located partially in and out of a larger crystal.
It facilitates bridging between the inner and outer worlds, between self and others residing on this planet, and between self and other worlds. The crystal aids in expressing that which one experiences when becoming more familiar with oneself. It is quite beneficial when working in aspects of spirituality and advanced metaphysical areas, and sharing this knowledge with others.
The Bridge Quartz crystal is also useful for all types of teaching, promoting communication and understanding between teacher and student.'
