    The author discusses some properties of the rhombus classes of degrees of unsolvability. The rhombus class is a generalization of \(D(0,0')\). The author analyzes in detail all the possible jump relations of degrees among the different rhombi. It is also proved that a lot of important results on \(D(0,0')\) can be extended to any unit rhomus.
