A truly extraordinary and one-of-a-kind antique articulated / mechanical snake ring from approximately 1850–1860s Europe, crafted in 18 karat
 gold using hollow gold construction, described as a "noble custom piece" — a dual-purpose design that can be worn as both a ring and a 
pendant. Most remarkably, every joint in the snake's body is articulated and can move independently, creating a piece that is "flexible like 
a pet in your hand"
