Post by MiB »

18 carats gold pendant (tested and confirmed by a jeweller) has 1 hallmark (750) and 1 stamp (diamond with the letter 'C' or 'O' + star + crescent + letter 'P'. Image Image I would like to ascretain how old is the pendant based on the manufacture's stamp. Possibly from France. Thank you
