The Provenance of Amber Ornaments Unearthed from Northern Wei Dynasty Tombs in Datong, Shanxi Province

Ancient amber serves as a crucial material witness to cross-cultural exchange between China and foreign countries. This study focuses on typical amber artifacts unearthed from Northern Wei Dynasty tombs in Datong, Shanxi Province. The specimens were analyzed using extended ultra-depth-of-field three-dimensional microscopic system, infrared spectrometer, Raman spectrometer, and scanning electron microscope. Complementary perspectives from archaeology and historiography were employed to explore the raw material sources, manufacturing techniques, decorative motifs, and cultural significance of these artifacts. The results indicate that the amber raw materials originated from the Baltic Sea. Some artifacts were locally processed using imported raw materials, while others were likely imported as finished products. The amber artifacts can be divided into plain and decorated types. Decorative motifs include string patterns, lotus patterns, honeysuckle patterns, and auspicious beast motifs. Both the shapes and decorative styles reflect the spread of Buddhist culture and embody the multicultural integration characteristic of the Northern Wei Dynasty.This study provides the first scientific analysis of amber unearthed from Northern Wei tombs in the Datong region, offering material evidence and a scientific basis for understanding ancient amber circulation and Sino-Western cultural and trade exchanges along the Silk Road.
