Do you mean the entire cap or just the jump ring that a necklace would hang off of?
The ring itself is a piece of cake. My girlfriend is a jeweler, and she could do this in her sleep. You need some wire of the right guage and a pair of pliers. The part that fits on the cap would be more of a challenge.
