**Summary:**For vector functionals on a $C^*$-algebra of operators, we prove an analogue of Glimm's vector state space theorem. We deduce that a\break $C^*$-algebra is prime and antiliminal if and only if the pure functionals are w$^*$-dense in the unit ball of the dual. We also give a necessary and sufficient condition for a convex combination of inequivalent pure functionals to be a w$^*$-limit of pure functionals.
