Enamel Bow Earrings - Sterling Silver - Vintage

Lovely vintage enamel bow stud earrings in sterling silver.  They measure approx 14mm x 14mm.  Some enamel loss but hard to tell as silver similar in color to pale blue enamel.  Backs are mismatched and one appears to be original and sterling other likely not.  Also note one of the posts is slightly bent but functional.  Price reflects.
