This powerful mini pyramid is 3 1/8" at the base and emits a scalar wave that mitigates EMF in your home or office. I call this a Unicorn pyramid for it's fun use of color. It has a piece of tumbled amethyst with a copper coil at the tip, cast in vibrant pink polyester resin. The base has iron shavings cast in lavender polyester resin. Amethyst is a powerful healing stone known to soothe the mind and emotions, and is associated with the upper chakras. People who use scalar energy devices report having better sleep, enhanced focus, meditation, and a sense of well-being.
