I just saw a necklace that's made up of pearls strung on very fine
gold chain. There is a space of about 3/4" between each pearl
which allows the chain to be seen. No crimps are seen. Do you have
any ideas on how the pearls are kept in place?
These are known as tin cup neckalces. The bulk of them that come
through my repair shop (I work for one of the big chains) have
pearls epoxied onto box chain. When I am asked to make one from
scratch I individually wire wrap the pearls into an open link chain
like a fine curb or figaro.
