It is always thrilling to find a patent number on an old piece of jewelry, mostly because it often leads you back to the original patent application and drawings. That's what happened with this necklace. It dates to the late 1920s (or very early 1930s) and has a unique chain made of large, fold-over clasps. The chain design was patented in 1928. You can read the full application, and subsequent referencing patents, right here. The necklace itself is beautiful, with convincing matrix on the turquoise glass and silver plating on all the metal. I have only seen one other example of this chain in person, on a piece that I sold in 2010. It was a bracelet set with faceted pink glass. I still think about that one!
