Many people are too quick to dismiss crystals that have been treated in some way, and ones that are man-made, and whilst many will make me shy away in horror, there are some that take on a whole new lease of life and are very energetic, and create new qualities. Colour has its own energetic vibration, so those that have high colour which you wouldn't normally find, have that enhanced energy signature added to the crystal vibration. Why not try them for yourself?
