We show the existence of self-dual semilocal nontopological vortices in a [Phi][sup 2] Chern-Simons (CS) theory. The model of scalar and gauge fields with a SU(2)[sub global][times]U(1)[sub local] symmetry includes both the CS term and an anomalous magnetic contribution. It is demonstrated here that the vortices are stable or unstable according to whether the vector topological mass [kappa] is less than or greater than the mass [ital m] of the scalar field. At the boundary [kappa]=[ital m], there is a two-parameter family of solutions all saturating the self-dual limit. The vortex solutions continuously interpolate between a ring-shaped structure and a flux tube configuration.
