Crystals have been desired and collected by people from all walks of life since ancient times. They are believed to have magical powers in Healing and Divination, although their beauty is most commonly utilised in jewellery. Perhaps this is because people understand these powerful energies, and need to have them close. Scientifically, Crystals are natural geological forms, which are created by the reaction and solidification of various chemicals. They have a regular, internal three dimensional structure which forms interesting geometric shapes. It is this complex structure and the way it affects light that has created a lot of the mysticism associated with Crystals.
