The Seal of Solomon is an occult tale from the Kabalists, I dont know if it was real or not, but considering Solomon's fall from grace, I wouldnt be surprised if it was at least in part true.
Kaballah is talmudic fanfiction. It's safe to assume anything from jewish "tradition" that isn't also in the Old Testament was made up after Hadrian flattened the temple.
King Solomon had a ring with the star of rephram on it. It gave him command over the demons.
