Vintage art deco inlaid enamel necklace, over copper

This amazing necklace is silver plated over copper. Inlaid enamel detailing, red stones appear to have veins of real gold or copper. Rectangular shape links of the necklace are intricately carved with an elaborate deco design. Barrel clasp. Beautiful condition. Plating is gently worn on a few of the edge pieces (thats where you can see it is real copper). I have seen compareable pieces in the 500.00 range that are not this elaborate.Photo's glare does not show the piece well.
