This is a lovely Georgian (circa 1780) hair ring, with a garnet surround. I am not listing it as a memorial ring. It's possible that it was, but these rings were often sentimental gifts to a beloved. Anyway, it is a size 7 and 1/4, and it weighs 2.79 grams, and is in very good condition. The decorated top of the ring measures 3/4 of an inch North to South, and almost 5/8 of an inch East to West.
