Wire wrap crystal: Cross two wires of the same length. Twist the middle of the wires to create a “backbone.” It should be as long as the longest flat side of your crystal. Place wire on longest part of crystal and start wrapping. When wires cross, twist them. Cover the crystal so that it won’t slip out. When finished, bring wires to the top and twist. Use twist to create a loop and tuck remaining wires in. See post get more details on how to wire wrap crystal.
