A simple relativistic model of heavy-light mesons is applied to the rare
decay B -> K* gamma in the standard model. We find Gamma(B -> K* gamma)/Gamma(b
-> s gamma)=(17 \pm 4)% and BR(B -> K* gamma)=(4.8 \pm 1.9) \times
10^{-5}(V_cb/.04)^2. These numbers are reduced by only 20% in the heavy-quark
limit.
