MATISSE Copper and Green Speckled Enamel Modernist Necklace is done in segmented linked squares. It is 15 inches wearable, adjustable downward. I believe the added link in the back is a replacement. The necklace that is just copper is 13 1/2 inches wearable, and someone added the link extender. It is 3/4 inch wide. A great looking piece, signed in a cartouche on the back in script, Matisse.
