Each piece is reticulated and finely worked to depict a flying peacock with its body turned, revealing the large tail featuring curious 'eyes', the body incised with detailed feathers.
Note:
A Jin dynasty 'bird holding lotus' example, see GU, Fang. The Complete Collection of Jades Unearthed in China, volume 2. Beijing: China Science Publishing and Media, Beijing, p 231.

Compare two pairs of Song dynasty examples, one with 'peacock and peony' decoration, the other with 'magpie and flower' decoration, both excavated from Yixian Gaomoxiang Dabeicun, Baoding, Hebei in 1986.

原以爲是納言——金人垂脚幞頭兩側、或女冠後部的巾環。但納言下部必有大孔，以便固定垂脚，本品沒有，又是雙面工，精雕細琢，更大可能是簪頭。

類似簪頭參見1986年河北省保定市易縣高陌鄉大北城村窖藏出土北宋孔雀銜牡丹鎏金銀腳簪、玉練鵲銜花金銀腳簪，現藏易縣文管所；以及安徽嘉山縣板橋西恭獻王李貞夫婦墓出土的玉鳳凰，係李贞夫人之物，夫人乃朱元璋二姊，卒于元末，玉凤凰係元代物，收錄于揚之水著《奢華之色：宋元明金銀器研究卷一》，中華書局2010年出版，第74頁。
