This lovely Maltese cross Brooch measures 1 7/8" by 1 7/8". The back is unsigned, but it has the number A1943. It looks a lot like the kind of number that Boucher used for their pieces. But from what I can tell, that number would be too low for it to be Boucher.
Nonetheless, it is beautiful, very well made and in excellent condition.
Message with questions. Thanks for looking.
