Vintage Victorian revival Art Nouveau Deco era Antique brooch pin 20s 30s 40s

Stunning Vintage Art Nouveau to art Deco era Antique brooch pin. I'm talking true 1920s 30s or 40s! Much of the pieces in that era seem similar to me... especially with the 40s having a Victorian revival. But the flow of the flowers is certainly Art Nouveau. Has an original c-clasp Excellent vintage condition for its age some light average wear and light discoloration or finish wear. I don't see any hallmarks or markings. Could use a very light cleaning.... but nothing really notable as far as flaws or damage.
