We study neutron stars with cores consisting of a mixture of constituent-mass quarks and diquarks. Diquarks are colored, two-quark bound states which have been conjectured to exist in the density range above deconfinement. We compute an approximate equation of state for such a mixture. At relatively low densities this has the form of a polytrope with adiabatic index Γ=2. We find that the maximum-mass star with a quark-diquark core surrounded by a low-density envelope of nucleons has mass 1.79Msolar, radius 11.4 km, and central density 1.8×1015 g/cm3.
