"Crystals are often used in Feng Shui to attract energy and focus it into an area. Because prismatic crystals take light and split it into rainbows the energy these crystals attract is balanced and harmonious. This 30mm (1-3/8 inches wide) bright red crystal is topped with a metal charm that says Happiness in Chinese. Comes with instructions for hanging for happy career qi (chi), happy relationship qi, happy family qi and happy extended family qi. Entire piece measures about 8.5 inches."
