Guilloche Enamel Locket - Sterling Silver - Vintage

Fabulous rare guilloche enamel locket with orange and yellow enamel and dainty gold flower accents.  I have never seen this combination of colors in a locket like this. Inside one side is a fabulous vibrant blue and the other side has a frame present with an old photo.  Measures 1 inch with loop at the top x just over 0.5 inches.  Stamped sterling inside.  Missing top jump ring but I will add a new sterling ring before shipping (won’t be soldiered shut).
