We investigate numerically the stability and evolution of two-dimensional soliton-like structures in the form of necklaces in media with cubic-quintic nonlinearity. Using a variational technique, optimal input propagation parameters for the long-lived stable solutions are determined. Analytical expression is in good agreement with numerical findings.
