The symbolism of the Jerusalem cross (also known as "five-fold Cross", or "cross-and-crosslets") is variously given as the Five Wounds of Christ, Christ and the four evangelists, or Christ and the four quarters of the world. It is used as a symbol of world evangelisation. In folklore, it can ward off vampires, incubi, succubi, and other evils.
The ornate red rhinestone brings the Celtic flavor of this pendant. The Crucifix gives it a spiritual attraction and special meaning. It's a crossing over from one age to another.
