In diversity, there is beauty and strength. Each set is made up of individual stainless steel springs & plated stainless steel springs (rose gold/sterling/gold/matte black) The PLATED stainless steel will not rust but will fade with wear and/or water. Because Dia are springs, they will stretch & rebound to an extent but WILL lose shape if pulled with force. Please be gentle while taking bracelets on & off. Roll on a few at a time!
