Jubilees use jewel and metal labels to mark anniversaries, with each name signaling a different milestone. A Silver Jubilee denotes a 25th anniversary, a Golden Jubilee a 50th, and a Diamond Jubilee a 60th. The plaque or circle at Miami University is described as a Diamond Jubilee, which means it’s commemorating a sixty-year milestone. Bronze Jubilees aren’t the standard label for a 60-year mark, and are far less common for campus commemorations. So the Diamond designation best fits a long-lasting, sixty-year celebration.
