I don't feel like looking too much into it, but the 王 in 琲 is really 玉, so yes, this kanji does mean "necklace".

And if you try to interpret this by pulling apart the kanji into its constituent radicals, then it rather suggests "not king", not "king of not [...]". So following your interpretation, it rather means "not the king of the world".
