He was 86. He passed away early on May 6, according to his son Dror Yehuda, president of New York-based Yehuda Diamond Co.

Yehuda, a native of Israel, created "the first set of digital scales for diamonds" and "the first diamond laser-cutting machine," Rapaport News explained in a 2019 article.

Among his other innovations were a clarity enhancement process, a color meter for rough diamonds and a synthetic-diamond detection device.

Except for a few years when he worked as an accountant, Jim Schwartz has always been a jeweler. He grew up in the business and after "counting beans" for a few years, he and his wife, Robin, opened Robin James Jewelers in Cincinnati, Ohio. "We were coming to a stage in our life where we knew we have to make a decision," says Jim Schwartz. He and Robin wanted to do it right, so they called Wilkerson. The best surprise (besides surpassing sales goals)? "The workers and associations really care about helping us move out own inventory out of the store first. It was very important to us."
