This gold cameo was inherited in an estate from my wife's mother, we believe it to be from the early 1940s as gift from her husband when he returned from WWII.where he served in Europe. It is mounted in a 14k yellow gold frame with a Pin or Pendant mounting (the bail for the pendant folds in for use as a broach see pictures).  The overall length is 1 1/2 inches and the width is 1 inch, the total weight is 7.2 grams. It is a very nice hand made piece.  It looks like the cameos that came from Italy during the same era. or earlier, however there is no hallmark or signature to be seen that I could find.
