Sterling Silver 925 Aqua Blue Enamel Dolphins Ocean Animal Dangle Necklace

Sterling Silver Aqua Blue Enamel Dolphin Necklace. I think it is by Zarah originally but it is not signed. The length is 18". Also, the sterling clasp is a replacement and is not original to the necklace. This has been in my jewelry box for years but I'm finally ready to part with it so someone else can give it the attention it deserves.  Please use the pictures as your main source of reference, but feel free to message me with any questions at all. Thanks for looking!
