Vintage Pearl and Silver Brooch

This is such a lovely brooch! It has a very fine silver mesh, larger texture ribbon mesh,, and smooth shiny silver, along with 3 large pearls. I could not find a similar one to compare, and found it has a lot of similarity to Mikimoto designs but none I could find exact. I also could not see any marking of the back. I believe it is probably from the 1940s-50s. Very dainty and just beautiful.
