Vintage Gold plated double Cuban or cable style chain necklace

GUC- vintage mid century modern necklace-It’s a thick flat chain with flat fold over hook closure. The design is like a double bolo tie with a gold embellishment- not sure what to call it (Art Deco, southwestern, or architectural maybe). Anyway, it’s so fashionable, looks high-end, and quite a statement! It’s possible to describe the chain as Cuban, cable, or double style chain. I’m not an expert- but it looks similar to these descriptions. Could be brass, plated, or just gold tone. It doesn’t stick to magnet. Small signs of tarnish on the back of the necklace- see pic.
