Long Metal Necklace with Beads

Unique long strand necklace with connected circles / loops with hanging green beads from each circle. Hard to describe - see pics. Center of necklace is multiple metal circles essentially - again - better to see all pics. Single lobster hook closure. Metal is a tie between a gold and silver color. Depends on the lighting. Approximate length (taken unclasped from end to end) = 35" Good condition with some minor darkening to the metal, but it looks like part of the design. <GY20>
