These DIY cracked marble necklaces have a "Frozen" look that our Girl Scouts are nuts over! Bake marbles at 350 F for 20 minutes, drop them into an ice bath, and watch them crack into a pretty pattern.
Caged Fried Marbles - nice accents to purses, earrings or pendants. The artist writes: "I used too small rings; it was a pain to hold marble still and hook rings over it. Those who have experience w/jewerly making will love. Not for me.
