This set reminds me of Miriam Haskell's work and might be from Japan or Germany from the 1960s, though it is not marked. There are green textured beads (almost "wedding cake" style but not quite), green faceted "prystal" beads, clear and AB coated beads, and gold spacer beads. The matching earrings are clip-on style and measure 1-1/4 inch by 7/8 inch. The longest necklace strand is 15 inches and the shortest is 11-1/2 inches, plus there is 3-1/2 inch beaded extension. There is some age-related wear to the necklace, but it is really hard to see unless you look closely. An amazing amount of artistic effort was put into this necklace, hard to find in modern jewelry.
