About the Presenter:

Stanley Zale

Stanley Zale has spent his entire life in the jewelry business. After seemingly spending every school vacation in the Zale Corp NY office, he began learning the diamond business as a teenager. His diamond cutting training included sawing, cleaving, and blocking. He spent several years working in, and then leading, Zale’s rough diamond buying, which included cutting and production operation in the days when Zale's was a DTC Sightholder.

After Zales was sold, he opened his own diamond manufacturing company in New York. He then spent nearly a decade working for legendary Diamantaire Louis Glick before moving on to his present position as Vice President, Diamonds and Gemstones for Stuller.

Besides learning so much from his Grandfather, MB Zale, Stanley considers himself very fortunate to be able to count Louis Glick and Matt Stuller as the strongest influences and teachers in his career.
