About Me

My name is Marcia Passos-Duffy and I’m the owner of Geo-Graphic Gems. Folks in the Monadnock Region of New Hampshire may know me as editor and publisher of regional magazines (Monadnock Table, The Business Journal and atHome Magazines). I not only love to produce new magazines, but I also love to collect vintage National Geographic magazines. I discovered a technique to transform older magazines into works of art quite by accident when a friend I was visiting showed me the work she was doing using natural acids on vintage magazines to make works of art on canvas. The acid dissolves the ink on the pages, creating brilliant marbleized designs. I began to do this myself and was intrigued by the stunning designs this technique created. I have made jewelry in the past for friends and I realized that bezels with glass cabochons would be an ideal way to use this paper to make earrings and pendants – the glass locks in the paper, making it impermeable to liquids, and accents and magnifies the designs. Most people have not seen anything else like it! Hope you enjoy your Geo-Graphic Gems as much as I enjoy creating it for you!
