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. Crystal is 30mm (1.25 inches in diameter). This beautiful clear prismatic crystal is paired with a banner that proclaims (Chinese) "Protect My Family" on one side and "Protection for Crisis/Disaster" on the other. Instructions for hanging and information are included. Entire piece measures about 8 inches.
