We study symmetry breaking via quark mass differences in a relativistic quark model where mesons are built from heavy (m B 3 GeV) spin -$ quarks and antiquarks. The meson (squared-)mass differences are linearly related to the number of strange, charmed, etc. quarks in the mesons. We show that the pr
