These Orgonite EMF Shield Room Grid Pucks are created in ceremony with my orgonite blend of elite shungite, black tourmaline, crushed quartz crystals, pyrite, copper, metal & bronze powder, designed to provide EMF protection, dispel disruptive frequencies, & promote energetic harmony. Each puck is 1.75” & contains a spiral to move & direct the energy as well as a copper-wrapped quartz crystal to create the powerful piezoelectric effect. The pucks are sold in sets of 4 to create a room grid (each unit = 4 pucks). Place a puck in each corner of a space to create a grid of protection, amplifying high vibrations while reducing energetic stagnation and converting dead orgone into fresh prana. They can also be placed near sources of EMFs and other detrimental frequencies such as routers, computers, and phones. Beyond personal use in the home, these sets are also great for practitioner spaces like reiki rooms & yoga studios. Please note that each set is handmade & one of a kind.
