J.Crew Ceramic/Metal/Rhinestone Necklace

This is a very unique J.Crew ceramic (or stone) necklace with rhinestone and brushed antique gold hardware. No chips and in excellent condition except for some discoloration on the back of several metal disks that hold the flowers together (shown in photos). I suspect that this is due to perfume but is in perfect condition from the front. Soft white matte flowers Measurements- Length: 20" to 23" Flower width: 2" and 2.5"
