This necklace starts with a foldformed copper square thats about 1.5 inches square. I added an oval-shaped stone of aventurine and then heat colored the metal. To show it off, it hangs from a necklace that is accented with nephrite and agate beads! Not your usual necklace - I get so many compliments when I wear mine! Keep in mind that each time I make this it comes out a little differently - the fold lines, the heat coloring and even the color of the stones may vary slightly.
