Lovely 1920s Art Deco Brooch, in a pretty blue that is a shade of cobalt. The white metal setting is typical of the era, and it has a "C" clasp on the back. 2 3/4" long.

The faceted blue glass stone has light in itself, it seems. Its flanked on either side with white paste stones.
This lovely pin would perfect to close the neck of a blouse or dress, or at home on a 1920s cloche style hat.

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”
