Tiffany Stevens Resigns From IGI

By Rob Bates | June 09, 2025

Tiffany Stevens has left her job as head of the North American branch of the International Gemological Institute (IGI), the lab confirmed to JCK.

No successor had been appointed at press time, according to IGI.

Stevens wrote on LinkedIn that she joined IGI to help “bring the company to the next phase of its evolution during a dynamic time, and at the end of last year, we officially rang the bell, lit the lantern and IGI entered the Indian public market.

“I was also delighted to expand upon my expertise by working at the intersection of science, global trade, sustainability, and technology, which the reach and impact of IGI positioned me to do.”

She added that “after spending the last several months working with the internal team and our board partners to ensure that we strategically leveraged our new standing to benefit the jewelry industry as a whole, I have made the decision to step down.”

Stevens joined IGI last July, after seven years as president and CEO of the Jewelers Vigilance Committee (a role currently held by Sara Yood). At IGI, Stevens took over from Avi Levy, who is now working for rival lab GCAL by Sarine.

IGI was purchased by Blackstone Group for $569.65 million in 2023. It went public in December.
