Hallmarks on jewelry are so important. The information is invaluable in providing where, when and perhaps who made the piece. They also give a sense of history.
At first glance this particular ring of 15k yellow gold gives the impression of being large in scale for its type. The stones, pearls and pastes are set closed back and the overall appearance is frilly and decorative with a wearable low profile.
From its hallmarks we know that the ring was made in 1886. It is set with two (2) diamond shaped almandine garnets, six (6) half natural freshwater seed pearls and seven (7) garnet colored pastes all in scalloped rub-over and pinched collet mounts. The north and south perimeters of the cluster are appointed with scroll and curved appliqués which mare similar in configuration to the incised patterns along the entire shank.
From the hallmark (as well as testing) we know this is made of 15k yellow gold and in Chester England. While we find no further information of the maker LB, hallmarks provide that too.
