I found what looks like some sort of a sea creatures' tail charm, but what I liked about it were the stones in it, so I found some beads that had similar colors and placed them on head pins that have loops on the end and connected them to a chain and some small loop ear wire with regular head pins.

and as a good rule of thumb, always disinfect any earrings before wearing... which is what I did after placing them on the floor for their photos! :P but ya never know who was handling them before you purchased them so just to be safe ;)
