This set is a little nutty, but still great.
The necklace is designed as a line of brilliant-cut diamonds, suspending at the front a fringe of seven graduated emerald bead drops (two of which have been added later). Each emerald drop has a diamond-set cap and surmount, linked by emerald beads. The necklace was made in 1960 by Van Cleef and Arpels and is accompanied by a matching pair of earrings mounted in gold.
I think it looks like pears or green acorns. Gotta love the 1960’s.
Here’s a closer look at the earrings.
