The mark on these lockets - which come in a variety of styles - is my absolute favorite. It is a bumble bee with the letters "RBM" on the top and the letters "ATRICE" on the bottom. Read top to bottom, the combination of letters and the image of the bee give you Beatrice. The year of the company's founding, 1874, is also a part of the mark. Adorable!
I just listed this locket in the shop this morning - go and have a look!
