Great info, thanks!!
I had to google "rosette", and some learning has occured. 8^)
Would it be safe to assume that this one was likely made between 1954 & 1959 when Cuba went to Castro? Or is this jeweler known to have stayed in business into the Castro years?
Would it be bad form for me to ask what something like this would be worth? I have no idea what it is made of but it is feels darn heavy too me.....
