WEISS Unusual Colored Pinkish Amber Rhinestone Set in Copper Necklace must be from the 50s or 60s. That is when copper was having it's heyday. The stones take on different color in different lighting, and I am not sure if it is because of the copper setting, or they are a similar stone to the blue stone we know as Sapphiret. It is a very pretty lady like piece and measures 15 1/2 inches wearable, adjustable downwards. The stones are variegated in size, and there is a larger drop at the end.
