Taxco Sterling and Black Inlay Necklace

Very pretty designed sterling silver necklace - approx 15" with triple design front featuring black enamel inlay.  the necklace is signed on the slide in clasp TR-18 which means this was made in Taxco, Mexico and the designer had the first or last name beginning with "R" and was the 18th to register. This is in very good condition, just needing a good clean/polish up to the buyer.
