Vintage thin silver & diamond choker necklace

Vintage thin, dainty & luxe-looking silver tone metal and faux diamond rhinestone choker necklace. The necklace chain measures 17.5 inches long (including a 3.5 inch extender) & has a lobster claw enclosure. The central part of the necklace is comprised of two chain strands - one is the original necklace strand & the other is a strand that is draped between sets of diamond rhinestones. One diamond on the bottom row is missing, but, since it’s in the middle, it sort of looks intentional.
