Green and Yellow Floral Brooch

Green and Yellow Floral Brooch. Pretty brooch, looks like it could be upcycled/handmade. Unknown maker, age, or materials. I think it’s a painted wood base with some type of material, maybe acrylic?, for the floral top. Colors include green, yellow, cream, orange, etc. Metal pin mechanism is glued on back. Good preowned condition. Pin part is straight. Opens narrowly and closes by locking in place with a turning lock, this is a little tight but works. Some stray glue on back where pin is glued. Surface cleaned, grooves could use a deeper cleaning. See all photos for measurements and condition.
