After many tries, I'm ready to admit that I lack the photographic skills necessary to shoot the mark successfully, so have rebuilt it in Photoshop; it's an accurate depiction. (The ring itself was shot in a black ring box.)
I've contacted the school's archivist, who knew nothing about the ring and, oddly, evidenced no interest in it.
Any info about the maker of this ring, or a ballpark date, will be gratefully received. -Pati
