Information and history of coral plus a gallery of coral used in antique and vintage brooches. Believed by classical civilizations to possess therapeutic and apotropaic powers and used as ornament since ancient times, coral was a staple of jewelry design in Victorian America. Coral is an organic gem, the skeleton of tiny marine animals called ‘polyps.’ During the mid-nineteenth century, when this demi-parure was fabricated, coral was mainly harvested from the Mediterranean waters surrounding Naples. American jewelers like Ball, Black & Co. imported Neapolitan coral and set the gems in mountings of their own design. Reference: The Metropolitan Museum of Art
