Everybody has a theory about who designed this necklace, I have given up because I love it, period. Apparently, someone changed the hook to remove the designers name, but when you have set with luxury all your life, it is easy to know this is one special necklace. This necklace is 16” long with the 2” drop and it is 2 ½” wide. The center stone is frosted and the deco roundels and the column glass make you feel like it is from the 1930s. it is all glass and very special to me.
