In modern times, crystals have seemed to be just pretty rocks for display. But as we begin to study them more, we are relearning and regaining the knowledge of our ancestors and using the natural energy of crystals.
Crystals and minerals throughout the ages have played various roles in societies. Many ancient civilizations have used crystals in jewelry, healing, pursuits of higher learning, and others in sacred ceremonies. The Egyptians used crystals not only in jewelry but also ground up poultices and elixir as well as for make-up. The bible mentions crystal usage too. One example is the breast plate of the high priest Aaron (Exodus) which mentions several stones, approximately 27 from various translations, which were used to provide protection, wisdom, and strength.
