Unsigned copper enamel necklace appears to be the work of Matisse. This is a design I don't see very often. Gray speckles on white enameling, with geometric shapes sandwiched between copper frames and backing. Attractive link construction along the top; the necklace has a very fluid fit. 18" length with hook and chain allows piece to be adjusted smaller if desired. Excellent overall condition with copper plating and enameling looking sharp! - $125
