Antique buying Stick Hat Pins

Product Name: Antique buying Stick Hat Pins
Set of 3 beautiful antique stick hat pins. There is a rose gold treble clef, a cultured pearl pin and pink stone pin (unsure of stone but possibly pink spinel, glass or ruby). None have been tested buying for metal purity, there is a marking on the pink stone pin but I cannot read what it says. These pins come with their own piece of history in the red velvet box from Jules Wendell & Son (1850-1900)!.
