Does your pin have a vertical stem instead of the normal horizontal one?  Then this is the converter for you.  Although it is showing with a small bail in the picture, you can select the size bail you need below. (See the pictures for the pin to pearls converter for an image of the larger bails.) In the picture with 3 views of the converter, the first is the side, the other 2 are the side of the converter that goes against the pin.  You will see there is a little pocket for the pin stem to slide into.  In the picture with the back of the pins, you will see you just need to slide the pin stem into the pocket, then fasten the pin.  You pin is now a pendant.  The pocket is fairly snug and there is not much movement of the pin in the converter. Please see this special shipping note when buying converters and chains.
