The prototype of Fermi mass matrices capable of accounting for Cabibbo mixings is shown to put a lower bound on Kobayashi-Maskawa CP-violation. The observed amount ε{lunate} = 0.002 of CP-violation in the KL-KS system in turn implies that 24 GeV ≤ mt ≤ 59 GeV; mt is the top quark mass. Assuming a vanishing weak (a la strong) CP-violating amplitude for mu→0, as strongly indicated by the data, ε{lunate} is formulated as a second order quantity in the fermionic mas hierarchy.
