Gorgeous, Vintage Signed Janice Girardi Sterling Silver and Iridescent Blue-Grey Abalone Oval Stud Pierced Earrings. 

   Each earring face measures approximately 5/8 of an inch, or approximately 15.87 millimeters, high, by about 7/16 of an inch, or roughly 11.11 millimeters wide, and about 3/16 of an inch thick. (Included is a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) The back of each earring is stamped, " 925", and signed, "JGD". Combined weight is approximately 6.5 grams, which includes the shell weight, of course.

 These are vintage earrings, which have been worn and enjoyed. They will have the expected light surface scratches and possibly tiny dings to the silver. No chips or cracks to the shell. The posts  both appear to be pretty straight, and the clutches hold securely. Hand polished, but there may be further tarnish to remove, if you choose.
  

   A very beautiful, very stylish, signed pair of vintage Janice Girardi Sterling silver and abalone earrings. Sleek, subtle, scintillating.
