In his more than 30 years at GIA, Shigley has been widely recognized as the face and voice of GIA research. Representing the institute around the world, he has lectured and published extensively on diamonds, colored stones and gem identification. His work solidified the institute’s reputation for groundbreaking research.

“Mr. Liddicoat believed deeply that GIA should have a strong research department, and thanks to Dr. Shigley’s work – from the very inception of his career – this vision is fulfilled,” said Tom Moses, GIA executive vice president of laboratory and research.

“Dr. Shigley’s selfless sharing of knowledge leaves a lasting legacy, not only for GIA but for the gem and jewelry industry.”

Shigley is a prolific contributor to gemological research. His studies identified methods of separating natural from laboratory-grown diamonds, documented important gem localities and established characteristics of HPHT laboratory-grown diamonds.

Shigley was instrumental in the creation of the GIA Gem Project, a collection of 2,800 stones (representing 225 minerals) from the Edward J. Gübelin Collection that is used for research, education and display.

Since 1984, he had authored or coauthored 195 scientific articles, including 79 for Gems & Gemology (G&G); 27 of those received the journal’s Most Valuable Article award. He serves as a contributing editor for G&G, and as the editor of the G&G in Review book series.

Shigley’s contributions earned industry recognition, including The Dr. Edward J. Gübelin Most Valuable Article Award (1998), AGA’s Antonio Bonnano Award for Excellence in Gemology (2007) and the AGS Lifetime Achievement Award (2017).

The Richard T. Liddicoat Award for Distinguished Achievement has been given to 13 people since it started in 1994. Several recipients are still at GIA today: Kathryn Kimmel, senior vice president and chief marketing officer; John Koivula, analytical microscopist; and Tom Moses, executive vice president and chief laboratory and research officer.

Wilkerson Testimonials

Retirement Made Easy with Wilkerson

The store was a landmark in Topeka, Kansas, but after 80 years in business, it was time for Briman’s Leading Jewelers to close up shop. Third generation jeweler and owner Rob Briman says the decision wasn’t easy, but the sale that followed was — all thanks to Wilkerson. Briman had decided a year prior to the summer 2020 sale that he wanted to retire. With a pandemic in full force, he had plenty of questions and concerns. “We had no real way to know if we were going to be successful or have a failure on our hands,” says Briman. “We didn’t know what to expect.” But with Wilkerson in charge, the experience was “fantastic” and now there’s plenty of time for relaxing and enjoying a more secure retirement. “I would recommend Wilkerson to any retailer considering a going-out-of-business sale,” says Briman. “They’ll help you reach your financial goal. Our experience was a tremendous success.”
