A delightful pendant./ charm 
Marked 9ct and probably English. I suspect it dates to the 1950's  but could be as early as 30's
The pearl is probably cultured at that age . 
In wonderful condition with excellent detail.
He is just over an inch long, not into the bale and weighs a good 6.5 gm , so fairly sturdy and ready to be your best friend.
( Chain for display only - sorry )
