Thanks for your input on this very MCM necklace; I believe it might be Amber. Love the flecks and pieces inside each piece. These pieces are quite smooth but not as heavy as the other Amber Set I posted. Could it be Lucite? Bakelite? Haven't done the "test" yet, but never seen flecks like these inside Bakelite. Love the MCM design! Appreciate your Input! Susana
