Cameo Dilemma

Friends, I need some jewelry design advice! I have this cameo pin (well, the pin apparatus is broken) that was my grandmother's and I want to do something with it. I am not a real wearer of pins. Rather than fixing it for a pin, I was contemplating turning it into a long necklace or maybe a shorter one? What do you think? Any other ideas? I am at the mercy of your design savvy!!

A little background: a cameo is made from a stone or shell cut in relief. Originating in either Grecian or Roman times (there is debate about exactly where), cameos were popular among several majestic monarchs, including Queen Elizabeth I and Catharine the Great. They developed a mainstream popularity during the Victorian Age (1830s-1900) when women's clothing was very dour and reserved -- and in need a darling little cameo pin to spruce up the neckline of an austere black dress. Cameos are featured as pins, necklaces, rings, and earrings.
