Finding age of cameo earrings, charm, and ring

by Christine
(New York, USA)

I have these cameo pieces that I am trying to set an age on and wondered if by their pictures and their styles you would know of what era they are? They all appear to be of true gold though only the band on the ring is stamped with
"14KcJ1" of "14KcJl". They were purchased as estate jewelry over 35 years ago and dont know how old they already were at that time.
Thanks for any information you can offer me!
