The wooden beads represent the part of the Cross that he carried up to Calvary. The red beads represent the blood that he shed after they whipped, beat, and shreaded the skin from his back with a weapon called the phlagrim. The purple Amethyst gemstones represents the robe that they put on him as he struggled to walk up to the place where he was to be crucified. The three silver crosses represent the two thieves crucified with him, one of the right hand, and another on the left. (Matthew 27:38). The black onyx gemstones represent that he died on that cross for our sins. Finally, the clear represents that he now lives inside of us "through" the Holy Spirit.
