I am looking for information on the hallmark marked Rio Grande. I have seen a lot of jewelry with this marking but can't find any info.

Thanks,

Christina

Rio Grande is a major U.S. jewelery supply house located in Albuquerque, NM. They have a wide variety of small items (such as charms, ring mounts, etc.) which they mark with their maker's mark and metal quality. Some of these item are sold finished to jewelers. If unaltered a jeweler usually does not change the mark on the item, if there is substantial alteration a jeweler may wish to (and should) use their own mark on the finished piece.
