I bought this lovely MIZPAH brooch and it has the maker'smark H&CB. In my research I found lots of similar sweetheart brooches for sale (mostly gold!) all with the same maker's mark but none of the listings were able to identify the maker. I would really appreciate it if anyone knows the maker.
Many thanks and hope you are all well,
