  We present the first concrete evidence for the classical stability of
vortons, circular cosmic string loops stabilized by the angular momentum of the
charge and current trapped on the string. We begin by summarizing what is known
about vorton solutions and, in particular, their analytic stability with
respect to a range of radial and nonradial perturbations. We then discuss
numerical results of vorton simulations in a full 3D field theory, that is,
Witten's original bosonic superconducting string model with a modified
potential term. For specific parameter values, these simulations demonstrate
the long-term stability of sufficiently large vorton solutions created with an
elliptical initial ansatz.
