As of August 2, we are no longer accepting submissions for the 2013 Gems & Gemology Challenge.

Participants scoring  75% or better will receive a certificate of completion (PDF file), and the names of those earning a perfect score will be listed in the Fall 2013 issue of Gems & Gemology.

Thank you for your participation, and we look forward to your entry in the next Gems & Gemology Challenge in 2014.
