These sterling silver chinese zodiac charms are perfect for making personalized jewelry. Shengxiao, also known in English as the Chinese Zodiac, is similar to Western astrology. It is represented by a circle of 12 animals and is based on the Chinese Lunar Calendar. Each calendar year is assigned to a certain animal and its associated attributes according to a 12-year mathematical cycle. The zodiac animals were carefully chosen for their lucky meanings and how they related to ancient Chinese people's daily lives. The 12 Chinese Zodiac animals are in a fixed order according to Chinese Yin and Yang Theory. The yin or the yang of the animals was based on the odd or even number of their claws, toes or hoofs and they are arranged in a "harmonious" order. Learn more about the chinese zodiac signs here.
