Identifying Gold Marks: Inquiry about 'NR' Mark on Telephone Pendant

Question
Hello my name is Jean & whilst browsing for info about a mark on the base of a gold telephone pendant I have came across your site where an enquiry from Fitts 11/20/2007 (I know it's long ago!) asked the ? any ideas on NR *Dukes I too have NR on mine & wondered if perhaps Fitts ever got back to you with HIS findings if it was a local mark. I am based in Surrey England UK look forward to hearing from you Regards

Answer
Hello Jean, I cant find Fitz question in my files . I am an Opal specialist , gold marks are always difficult. My best guess is NR is the the name of Maker * Dukes may be his trading store or brand name . If I can find out any more Ill get back to you , sorry I cant be more helpful  regards Rod
