The jade material and carving style of this object is similar to those of Liangzhu Culture Jade Trident unearthed from Fan Shan Graveyard.
According to “The Identification of Chinese Jade Artifacts” by Prof. Chien & Tan, some of the Liangzhu jade artifacts have shown twisted in shape or form changed due to the occurrence of extraordinary conditions of the environment where those jade artifacts have been buried.
This kind of conjecture seems not conform the common sense of the principle of physical sciences. Based on the principle of physics, such kind of material change in form needs a particular state of conditions similar to the original ones when the nephrite was formed billions of years ago. Furthermore, if such a shock effect has happened to the Liangzhu jade artifacts, it would have happened to everything in the surroundings which seems not the case.
As a matter of fact, the abnormal shapes are not uncommon for many Liangzhu jade artifacts found. This phenomenon may be explained by the reason that raw jade should be fully utilized due to its scarceness. The jade artifacts are carved by as wasting less material as possible. The abnormality is due to the way original carved not due to the shape changed by outer force. It is not impossible that there are some kinds of particular cultural traits that are known yet.The jade Cong of Liangzhu Culture shown on this website is found the curved cut in each section of the queen’s crown which may be interpreted as the recording of the pass away of the queen. This consideration may help to clarify the factors affect jade identification.
Dated back four to five thousand years, Liangzhu Culture mainly covered the area of Lake Tai in southern China. The varieties of jade artifacts of Lanzhou Culture are rich. They include jade Cong which is the most popular jade item, jade arched plaque, jade septic, jade trident, ax-shape plaque and jade cicada. With the spirit’s face as a major motif, the Liangzhu Culture jade artifacts are featured slim incised lines. The extraordinary elegant workmanship of Liangzhu Culture jade artifacts are always touching the hearts of professional collectors worldwide at all times.
The jade artifacts of Liangzhu Culture have three significant elements worth considerations. The first element is the impact on the motifs of jade artifacts of the later periods. For example, the god’s face motif constitutes the major motifs of the Spring and Autumn Period. The curling claws shown under the God’s face constituting the claws of the dragon for the Shang and Western Zhou dynasties. Second, many Liangzhu Culture jade artifacts with smooth cut marks on the surface of the jades of which the reasons behind that are still unknown. Third, many Liangzhu Culture jades are carved with the shape not in proportion to the boundary of raw material. This is the practice called carving under the limitation of the size of the material. This is the practice that let the carving object bigger with an imperfect proportion of artwork rather than carving smaller object with perfect proportion of artwork.
