There are a lot of generic parallels one can make, but it seems to be merely a power metaphor. Every major villain/tyrant must have a source of power, and that power is sometimes a weakness. Sauron had the Ring, Morgoth had the Silmarils borne aloft in his iron crown. It doesn't seem to be purposefully distinct as much as it is showing how "weighty" the silmarils are.
