This is a vintage silver charm of a ladybug.  It was enameled in black, white and red; there are some surface chips to the black.  It is marked on the bale, but I can't make out the mark.  It is at least 800 silver, and has a great patina.  It measures 5/8 of an inch high and just over 3/8 of an inch at its widest and weighs 0.8 gram.
