Even though this flower differs from the rest of the discs, we have included it in this chapter because of its shape and thickness. This type of flower is not depicted in professor Cheng Te-k’un’s book ‘Jade Flowers and Floral Patterns in Chinese Decorative Art ‘. We found a similar type of flower which was dated to the Song period (AD 960 - 1279) in an auction catalogue. Is our flower perhaps also from that period?
