Very nice Gold tone US Naval Seal and Coat of Arms stating “Ex Scientia Tridens,” Latin for “From Knowledge, Seapower.”. The seal was submitted to the Department of the Navy and officially adopted on January 25, 1899. The seal of the Naval Academy has been featured on every class ring since 1906. First class (senior) Midshipmen traditionally wear the ring with the seal facing outward and the crest, unique to his or her class, facing inward. Upon graduation, the ring is reversed so that the seal faces inward, the position closest to the heart. It can also be found on other jewelry such as this brooch and Navy souvenirs. In good vintage condition may show minor signs of wear due to normal use and age. Please refer to the pictures for the measurements. Shipped with USPS First Class Mail.
