This large orgone pyramid has a remote control LED light that changes colors, which is not only pleasing to the eye but can be used for color therapy. 5 1/2" at the base, it has a large piece of double-terminated quartz crystal wrapped in copper wire, a large piece of hematite, shungite, blue kyanite, and a beautiful piece of tumbled labordorite cast in clear polyester resin. The base has brass and aluminum shavings cast in turquoise polyester resin. LED light is powered by three AAA batteries that are easily replaceable. The remote control can set light to any color or set it to change colors in a sequence.
