Gravitas (from Latin) is a quality of substance or depth of personality. Gravitas (specifically dignity, seriousness, and duty) is one of the several virtues that ancient Roman society expected men to possess, along with pietas and dignitas. "Gravitas" should not be confused with "gravity" in the sense of importance, although they have a common etymology, coming from the Latin for weightiness. For examples of use, see the Wiktionary article.
