Jewelry advertisements are of interest to some collectors and researchers because ads can help to date the manufacture of a vintage costume piece. The images in this section appeared in trade publications (such as catalogs of jewelry wholesalers or manufacturers) or consumer publications (such as fashion or general-interest magazines). The source of the image is indicated. As we acquire additional ads, we will post them here. Ads are organized by jewelry maker name.
