Fab Antique 1920s Art Deco Necklace and earrings, otherwise known as a demi-parure. The set consists of a gorgeous and superbly designed necklace, 16" long, with an amber glass chain with some brass filigree spacers. Then there are the three triangles of yellow amber faceted glass, each framed with amazing filigree.
It is so 1920s, utterly Art Deco.

The earrings are square cut glass with screw backs. While they came with the necklace I'm not sure they were originally a set. But wearing it together would certainly match adequately. They measure 3/4".

This type of Art Deco and 1920s style jewelry brings to mind film and TV productions like “Miss Fishers Mysteries”, “Timeless”, and “ The Great Gatsby”
