Huge vintage Art Deco brooch, chrome and pink 'Peking' style glass cabochons, streamlined space age design, so unusual

Very unusual, large vintage Art Deco brooch with pink 'Peking' glass cabochons and shiny silver tone. I haven't seen another quite like this one, but imagine it is likely to be European, possibly German for example from the Jakob Bengel factory.

This piece is very large with a longer length of 2.75 inches and a width of 1.75 inches. It fastens with a simple hook clasp and pin on the reverse. The brooch is in good vintage condition with minor issues in the form of tiny dents to the outer edges of the circular cup settings - as you can see from the pictures, very minor.
