Monica Naranjo is a potter from Santa Clara Pueblo. She seems to specialize in creating miniature black jars and decorating them with sgraffito designs. I think she learned her techniques from her mother, Geri Naranjo.
Some of Monica's pottery is signed "Monica Romero," some is signed "Monica Naranjo." These days she's divorced, taking care of her mother and signing "Monica Naranjo".
