Crystals with the most diverse colours created by Pachamama. Each with a specific programming, with one or more distinct healing ray.
As a purist myself, I do not work with crystals that are dyed, auras, or synthetic. This is because most of the time, I cannot know the type of frequency they emit, which may even be in disharmony (as I have had the opportunity to confirm in some, via scientific machines that measure the atomic frequency).
So, I only work with the pure energy of the subsoil, which has the same energy of our body, of our human dimension and that the human body recognizes.
