Runes?

Hiiiii northwest crystals, me again. I am currently researching runes as I think I would like to put one on the back of a citrine necklace I’m currently having made. Does anyone with more knowledge than me know which one is the most powerful or a must to have on you? Obviously citrine is a manifestation stone so I was thinking I’d like to go down that path. Or if you know of any other symbols that would be good?

Thanks guys 💗💗
