More information on the PGQMEM Crystal Pendants:
The pendant is called ‘ARK Crystal’ and is commercially available.
Advanced Resonance Kinetics (ARK) crystal technology is a 25-year project of research
and development by physicist Nassim Haramein, released in October 2017. ARK
crystals are a ground-breaking technology that produces life-enhancing benefits, resulting
from an increased energy-coupling with the structure of the quantum vacuum.
