Discovered in 2016 and unveiled to the public on June 16, 2022, the Gold Leaf with Twin Phoenixes and Floral Motif is a stunning artifact from the Silla Kingdom. Made of 99.9% pure gold, the 0.3g leaf is pressed to an astonishing thinness of 0.04mm. Within a frame just 3.6 cm wide and 1.17 cm tall, two pigeons and a cluster of blossoms are intricately engraved with near-microscopic precision. The lines, thinner than a human hair (under 0.05mm), were carved using a jogeum (metal engraving) technique with fine tools like chisels and burins. The patterns are virtually invisible to the naked eye — only magnification reveals the unmatched craftsmanship of Silla goldsmiths and their mastery of micro-scale metalwork.

Digital twin using RTI technology

To digitally preserve these exquisite patterns, TRIC employed Reflectance Transformation Imaging (RTI) that uses a dome of directional lighting to capture fine surface details from multiple angles. RTI enables the visualization of even the most subtle textures, like shallow grooves or tool marks, which traditional 3D scanning might miss.

This artifact is now recognized as one of the most sophisticated examples of ancient Korean gold craftsmanship ever unearthed. The physical piece and accompanying video are featured in the Gyeongju National Research Institute of Cultural Heritage’s special exhibition, “Golden Birds and Blossoms on 3cm of Gold” (June 17 – October 31).
