I have not figured out who made these, heavy, well made sterling silver symbol earrings.  Omega clip pierced backs.  I see '87 on them, and Sterling, and MME.GELLA, unknown designer or who owned these and had the name put on.  Measures 2.5" in length.  Weighs 29.5 grams of sterling for the pair.  One clip is a bit loose as far as being tight on the pierced back, may need some adjustment.  Thanks for looking!
