Crystal pyramids, built according to the Great Pyramid's geometry, have special healing powers. Use them by tapping (no special training needed).
Over 5 - inch ones can create two tones (base and side taps).
Made of over 99.99% pure American quartz crystal, they have higher vibration and gentler resonance than singing bowls and gongs.
They're useful for crystal repair, sound therapy, etc and can be used with Reiki, Chiropractic, etc.
Simple to use: gently tap 3 times with a music hammer/stick for sound - therapy sound. Only crystal sound - healing products can emit tones corresponding to body chakras.
