Chinese people guarded the art of silk making for thousands of years, successfully keeping it a state secret. This secret paved the trade route between East and West, combining the cult history of both worlds in one craft. The silk enigma is probably what makes it so fascinating. Engraved with a high-relief technique on the 45mm silver coin, the silk moth perfectly complements the gilded mulberry against the background of scattered mulberry leaves. The combination of natural and human creation was forever locked in a 2 oz silver coin as an extension of the fascinating Natural Architects series.
