This single neck ring represents a fraction of the wide repertoire of silver jewellery made, worn and exchanged by highland communities in northern Thailand. Large neck rings were worn in tiered sets or with a chain and pendant known as a ‘soul lock'. This type, which can be made solid or hollow, is worn by the Hmong, Yao, Lahu and Akha.Silver was valued more highly than gold by many highland communities. Silver jewellery was a way of investing a family’s wealth to be passed down as heirlooms. It was also believed to have protective properties. Today, where security maybe a problem, silver is kept locked away while aluminium is used as a substitute.Originally, highlanders from China, these nomadic groups have recently begun to move southwards into mainland Southeast Asia.
