We report the discovery of two new circumstellar ring nebulae in the westernCarina Nebula. The brighter object, SBW1, resembles a lidless staring eye andencircles a B1.5 Iab supergiant. Its size is identical to the inner ring aroundSN1987A, but SBW1's low N abundance indicates that the star didn't pass througha RSG phase. The fainter object, SBW2, is a more distorted ring, is N-rich, andhas a central star that seems to be invisible. We discuss these two new nebulaein context with rings around SN1987A, Sher25, HD168625, RY Scuti, WeBo1, SuWt2,and others. The ring bearers fall into two groups: Five rings surround hotsupergiants, and all except for the one known binary are carbon copies of thering around SN1987A. We propose a link between these rings and B[e]supergiants, where the rings derive from the same material in an earlier B[e]phase. The remaining four rings surround evolved intermediate-mass stars; allmembers of this ring fellowship are close binaries, hinting that binaryinteractions govern the forging of such rings. We estimate that there may beseveral thousand more dark rings in the Galaxy, but we are scarcely aware oftheir existence due to selection effects. The lower-mass objects might be theequatorial density enhancements often invoked to bind the waists of bipolarPNe.
