Using data recorded by the CLEO III detector at CESR, we have made measurements of some properties of the Sigma_c^{*++} and Sigma_c^{*0} charmed baryons. In particular: Gamma(Sigma_c^{*++})=14.4^{+1.6}_{-1.5}+-1.4 MeV, M(Sigma_c^{*++})-M(Lambda_c^+) = 231.5+-0.4+-0.3 MeV, Gamma(Sigma_c^{*0})=16.6^{+1.9}_{-1.7}+-1.4 MeV, M(Sigma_c^{*0})-M(Lambda_c^+) = 231.4+-0.5+-0.3 MeV.
