"We are delighted to offer these beautiful Orgonite Pyramids from India. Orgonite is a combination of resin, metal shavings, copper (or other metals) and crystals poured into a mold. Clear Quartz is usually the most popular choice, but some pyramids can contain or even Agates. Orgone is another name for the life-force energy (or chi or etheric energy) which surrounds every living thing. It may be positive, negative or neutral. Orgonite therefore, is a tool that basically transforms negative energy into positive, by naturally attracting positive, etheric energy, and converting the negative Orgone into positive ions. This in turn, creates a more balanced, healthier atmosphere. Orgonite can work remarkably well on balancing all of the chakras, cleansing the aura and therefore improving both mood and health. It is often used to combat the effects of electromagnetic pollution or smog that arises out of electrical devices in and around our homes. Place a pyramid in your garden and notice the healthy growth that your plants/flowers/trees will experience. Use a pyramid in a childs room to alleviate nightmares. It can also help to relieve insomnia. The pyramids can contain a variety of crystals and minerals including, Amethyst, Clear Quartz, Rose Quartz, Tiger's Eye, Black Tourmaline, Green Aventurine, and Yellow Jasper. As each one is beautiful and unique, please let us choose one for you."
