New vintage opal moonstone ornate pendant necklace

New vintage opal moonstone ornate pendant necklace Quick list New vintage c. 1970s. Artistic Jewellery (Canadian company). Costume gold tone metal. Not sure what the stone is: opaque, opalescent. Faux or natural opal or moonstone. It’s very white opaque “milky” but reflects everything in the pictures. Pink purple blue yellow tinges in the milky cloudy stone! The gold ornate frame is gorgeous! 2 faux diamonds, 2 sundisks on the four corners. Very deep base. Heavy solid metal! Looks like an antique from the 19th century! Victorian or Something Dowager Violet from Downton Abbey might wear! 😀 Note: most of the vivid blue and black in the stone is reflected from my phone and boxes behind the scenes.
