Two Piece Rhinestone Mourning Brooch

I believe this to be a mourning piece - from an estate, it consists of two pieces. The top piece has a cluster of three heart shapes each accented by black and dark green, amber rhinestones. About 2-1/4" x 1-1/4".  The bottom part features three rhinestone chains with matching bottom designs. It measures 1-1/4" across and 2-1/4" long.  All japanned or black enamel metal. There is a small hole mechanism at the top of the stationary brooch which suggests it could also hang or be sewn.
