Antique 1920s Art Deco Necklace Demi Parure Amber Yellow Glass Stones Triangle Cut Brass Filigree 16" Flapper
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”
