Using algebraic dynamics and matrix diagnization, the geometric phase of a non-symmetry 3-particle spin chain has been calculated. The dependence of the geometric phase of this system on the algebraic structure of Hamiltonian is studied. It is found that when the algebraic structure of Hamiltonian is broken, a drastic change in the structure of the geometric phase takes place.
