Super silver?

Hi All. Lately I’ve heard some radio ads from Steven Singer Jewelers
in Philadelphia promoting “Super Silver”, made from Argentium.
Instead of tarnishing, it get’s “whiter and brighter” Huh? Argentium
may be great stuff, but is this an accurate description? I think
buyers might be doomed to disappointment. Beware of over-hyping even
something good!
