This is a theme collective of hearts that can be used to start a charm bracelet or a charm necklace one of.
There are 5 lockets out of the 12 in total heart charms.

One of the hearts is gold filled with a shell cameo looks to be Victorian and one American military sweetheart locket WWII
,some of the hearts are puffed, and some are sterling silver, a great starter for a charm necklace.

Some of these are really old and will add real charm to whatever you design.
I welcome your questions prior to bidding.
