14k yellow gold heart pendant Clyde Duneier CID amethyst Feb birthstone diamond

Pretty little pendant - dark purple faceted heart-shaped amethyst gemstone prong-set in 14k yellow gold below one small prong-set clear diamond. Rabbit ears bale. Would make a nice gift for someone whose birth month is February - or for Valentine's Day. Back marked "14k" and "CID" for designer Clyde Duneier. Approximate measurements = 1/2" long/tall X 1/4" wide/across. Gold-tone 17" box chain necklace spring ring clasp in some pictures will ship with the pendant - chain is not gold but is 925 silver with gold-tone metal overlay. Very good condition - nothing wrong with it - in fact, Seller recently had it polished and refurbished. Seller doesn't know when or where it was made - but it might be vintage/20+ years old.
