We show how the length scale hierarchy, resulting from different interactionstrengths in an optically-trapped spin-1 sodium-23 Bose-Einstein condensate,can lead to intriguing core deformations in singular topological defects. Inparticular, a point defect can be unstable with respect to the formation of astable half-quantum vortex ring (an Alice ring), providing a realistic schemeto use dissipation as a sophisticated state engineering tool. We compute thethreshold for stability of the point monopole, which is beyond the currentexperimental regime.Comment: 4 pages, 3 figure
