These pieces have me fascinated. The lot consists of interlocking pieces so in the end, you can make a bracelet and necklace, a long necklace, or, three bracelets. The pieces snap together. Each are four-strands long with deep yellow, red, and green. The connected elements are green and red striped enamel. Two sections are 8" long and the third is 9 1/2" long. 

There are no hallmarks but it has been suggested these might be by Kenneth Jay Lane. I'm not sure about that, but I do know they are a sensational collection of flexible jewelry. Condition is very good to excellent.
