I had the gold tested and it wasn't quite 14 karat but it tested way stronger than 10 karat.  This Victorian bar/collar pin is accented by black enamel (some is worn off--see photos) and 3 seed pearls.  Also, please look at the back of the pin and you will find that someone, some where along the way used soft solder on the pin...the black areas.  All things considered this really is a beautiful Victorian pin.  Would look spectacular on the lapel of a blazer or across the top of a blazer chest pocket or a scarf, or pinned to a strand of pearls....ahh the possibilities are endless!!  Circa:  Victorian
