Small white agate disc decorated with a Yin Yang symbol in the centre and the Eight Trigrams (Pa Kua) on the rim. Yin and Yang are symbols which represent opposite forces that are actually complementary. Inside the Pa kua they represent a balance in Feng shui which is a Chinese philosophical system of harmonizing everyone with the surrounding environment. Each of the ‘Eight Trigrams’ consists of three lines either ‘broken’ or ‘unbroken’ which were used in Taoist cosmology. Each trigram has a meaning for instance Heaven (天 Tiân), Lake (澤(泽 Zé), Fire (火 Huǒ), Thunder (雷 Léi), Wind (風(风 Fēng), Water (水 Shuǐ), Mountain (山 Shān) and Earth (地 Dì). This type of flower is not depicted in professor Cheng Te-k’un’s book ‘Jade Flowers and Floral Patterns in Chinese Decorative Art ‘.
