Members of the American Jewelry Design Council (AJDC), a nonprofit education group formed in 1988 to promote American jewelry design, donated a collection of 29 contemporary jewelry pieces to the GIA Museum in 2004 − the first formal collection of jewelry to the Institute. The collection consists of classic signature pieces that capture the designers' aesthetics and techniques and unusual, eclectic gems.
