What is Feng Shui you ask...Developed in China over 3,000 years ago, Feng Shui is an ancient science and art of luck. The word Feng means wind and Shui means water. Within the Chinese culture these two natural elements, wind and water, are associated with good fortune. Who doesn't need that? The base of these New Jade Star of David Feng Shui sets measures 54mm in diameter. Each set has six 12mm New Jade balls and one 16mm New Jade ball. Jade is known as "the stone of heaven" and the Chinese value it above both ivory and gold. Jade is known as the money attracting stone, I think we could all use a bit of that. What a deal, these were originally $30.00.
