GIA Offers Jewelry Forensics Seminar At Carlsbad HQ
The two and a half-day session will teach students to determine how jewelry is made using forensic methodology.

Carlsbad, Calif.—GIA will host its first seminar on jewelry forensics this August at its California headquarters.
The two and a half-day seminar, led by GIA instructors, will take students through the 12-step forensic methodology process to determine how jewelry is made, using GIA’s “Quality Assurance Benchmarks” as a guide to assess the workmanship.
“Participants leave with usable information and practical techniques for assessing the quality of new or vintage jewelry and how to effectively communicate their assessment of the jewelry’s engineering and workmanship,” said Elizabeth Brehmer, GIA technical advisor of jewelry manufacturing arts, in a statement.
Students will learn how to identify common manufacturing methods and how to discuss jewelry design, engineering, and workmanship using jewelry terminology.
Other seminar topics include the characteristics of precious metals and their compatibility with jewelry manufacturing, and how to pinpoint the factors that can affect jewelry quality and lead to jewelry failure, such as design and engineering.
Participants will receive a guidebook and a thumb drive with supplemental reference and jewelry case study information.
The first seminar session will be held August 5 to 7 followed by another session October 21 to 23, then another from November 4 to 6.
The cost of the seminar is $1,195.

The Carlsbad campus is also offering two lab classes this summer on jewelry repair and setting.
A “Basic Repair and Setting Lab Class” will be offered August 12 to 26 and an “Intermediate Repair and Setting Lab Class” will be available from August 19 to 23.
