David Sereda demonstrates crystal energy pendants derived from his research into solid-state physics, sacred geometries, and resonant & ambient fields. His firm, Light Stream Technologies, has taken this research into crystal energy and combined it with solid-state physics to produce these unique pendants. David Sereda describes the manufacturing process involved with creating the pendants, which involves inscribing sacred geometry into the surface of a aluminum disk to create a harmonic waveguide for some, and others use windings around semiprecious stones to focus crystal energy.
