You can charge any object with your energy of choice, be it element or simply "protection" "beauty" "luck" etc. I have a dragon ring that I charged with protection. The thing burns and itches when I'm near negative energy or in danger (IE: a bad neighborhood).
You think/focus on the energy you want to charge it with and push the energy into the object. Keep pushing until it seems "full". Usually it gives resistence and the energy you're putting in stops entering the object and sort of "leaks" around it. I seal the object with breath afterward and whisper to it what I want it to do. Everyone has their own style however.
This is also the way to create/empower amulets, talisman, and use gemstones in magick.
I charged an amber ring with beauty for fun when I was a teenager. When employment was hard to find, after my daughter was born, I took up a job as a waitress. I wore the ring not remembering what I had charged it with, and my tips were better! I never flirted like so many do, I was happily married and told many exactly that. The tip increase was not only from men but women too. Doing a little research in psychology, I discovered that all people (male or female) feel a natural unconscious like toward attractive people (inside and out), which is why advertisements are full of them. My ring turned out to have a perk I wasn't aware of that ended up aiding my family financially. "Beauty" enchantments for those who do not know, bring more attention to your attractive traits and cause your flaws to be overlooked.
