Vintage 14k Yellow Gold 4 Garnet Gems Butterfly Stick Pin Lapel Brooch

Vintage 14k Yellow Gold 4 Garnet Gems Butterfly Stick Pin Lapel Brooch. I am not sure if the item that screws into the pin is real gold or not, as it’s not marked, but the Stick pin is marked 14k. I also noticed that the very bottom tip of the pin is bent (please see photo). I know nothing about this item as I did get it from an estate, so please reference pictures for condition, etc., as this item is sold as is. If you need more pictures, please let me know.
