The main ingredient is polymer clay. I also use nickel free metal, sterling silver, or silver plated jump rings, chains, and closures for construction.
Pieces can be created or customized in any color, size, or length. Polymer is available in metallics, such as gold, silver, and titanium. It also transforms to look like gem stones such as jade, opal, ruby or sapphire. Polymer is very versatile and very lightweight.
