Chi Vital Energy Generator (Reiki) with Chakra Stones. The Chi generator is made of natural stones and silver-plated copper, consisting of seven six-sided points, each connected to a conical pyramid. Each point features one of these stones corresponding to one of the chakras: Amethyst, iolite, moonstone, peridot, citrine, carnelian, and garnet. The conical pyramid measures approximately 2.5 cm at the base, and each point is approximately 2.5 cm long. The weight is approximately 60 grams. As they are handcrafted pieces, the measurements vary from one piece to another. There are six different stones to choose from: Crystal quartz, amethyst, lapis lazuli, sodalite, orange aventurine, and red jasper. This generator is a device that collects and channels the dispersed Chi vital energy in the environment. This energy, Chi, is also known as orgone energy, Reiki energy, and Prana.
