VTG Coro Seashell Brooch Pin Synthetic Light Blue Silver Tone Coastal Rare 2"

This vintage Coro brooch pin features a round seashell design with a synthetic light blue material and silver tone color scheme. The coastal nautical theme makes it suitable for occasions like anniversaries, birthdays, and Valentine's Day. Made of acrylic with rhodium plating, this fashion jewelry piece is signed by the brand Coro and has a prong setting style. It is a unique and original piece from the United States, perfect for women who appreciate vintage accessories. This piece appears to have rhodium plated metal which makes reading the Coro maker's mark more difficult, this being said, we posted a picture of the makers mark and were able to confirm using an Amscope trinocular microscope. This is nice MCM brooch with a C or Copyright stamping so is post 1955. This 2" Coro brooch pin is in good pre owned clean condition, minor use wear on the metal, the clasp closure functions properly, excellent shell cabs. Please review pics for details, thank you.
