VTG Mother of Pearl Brooch Lot WW2 SweetHeart Pin Ducks Mid Century Shell 40s

Lot of 2 beautiful older brooches . Probably date to 40s or prior I like how the pin back on the ducks is embedded in the shell rather then just glued on Measurements: Carved mother of pearl ducks with silver metal backing: 2.35" x 1.25" / 9.36 grams Vintage "Mother" sweetheart pin . carved shell. Articulating gold filled (?) heart with glass stone: 1.5" x .75" / 5.94 grams Both in good pre-loved condition with tarnish and wear consistent with age. The "mother" pin has more tarnish, the ducks are pretty good.
