Abstract:	A ring-vortex soliton (RVS) is unstable in a uniform microcavity polariton condensate (MPC). We propose a method for generating a stable RVS in an MPC subjected to a ring-shaped defect potential. The density distribution of a RVS with a pump strength is obtained numerically for a given defect size and strength. Then we discover two types of RVSs: soliton with a dark ring and soliton with a gray ring. And the stabilities of RVSs are dependent on the pump and defect strength.
