Groovy Vtg Huge MOD Colorful 1960s Foil Lucite Translucent Oval Brooch Pin

This is a groovy huge authentic 1960's translucent Lucite brooch. It features foil accents with marbled Blue and Orange color. The back bar pin is screwed in place. I believe this to be a very special find that was made by a true artist but it is unsigned. Please let me know if you may know who made this. It is in wonderful vintage condition. I will note one spot on the front where the embedded foil caused a small blemish to the glass like finish. This is estate fresh to you.
