The glass maker who created the material for this flower came very close to a celadon green color which is commonly seen amongst jade flowers. The chips and air bubbles however reveal that the material is not jade but glass. Nevertheless the carving is not bad at all and the flower clearly has age. This type of flower is not depicted in professor Cheng Te-k’un’s book ‘Jade Flowers and Floral Patterns in Chinese Decorative Art ‘.
