“My work explores the vague line between the natural world and the artificial one,” says Jennifer Gierka. “Plastic elements combine with enamel and felt to create pieces that exhibit a strange ambiguous ‘nature.’” Her brooch is made of copper, enamel, felt, and plastic. 4 x 3 x 2 in. (10.2 x 7.6 x 5.1 cm). Photo by Mark Johnston. This piece appeared in the November 2009 issue of Art Jewelry magazine.
