  A previous work gave a combinatorial description of the crystal $B(\infty)$,
in terms of certain simple Young tableaux referred to as the marginally large
tableaux, for finite dimensional simple Lie algebras. Using this result, we
present an explicit description of the crystal $B(\lambda)$, in terms of the
marginally large tableaux, for the $G_2$ Lie algebra type. We also provide a
new description of $B(\la)$, in terms of Nakajima monomials, that is in natural
correspondence with our tableau description.
