Christie Romero, a nationally recognized antique jewelry historian, gemologist, instructor, and author, opened the 2004 Gemological Institute of America (GIA) museum lecture series in March with "Gems and Jewelry: A Timeline of Discoveries and Techniques." Romero presented a detailed timeline of gem discoveries and their influence on jewelry dating from as early as the 13th century B.C.E. through modern times. Along with several staff members of the Richard T. Liddicoat Gemological Library and Information Center at GIA, Romero researched and found hundreds of intriguing examples of jewelry from these historic eras. The museum lecture series is open to the public on a space-available basis, and seating is limited. The entry fee is $10 per lecture.
