About Lazare Kaplan

The Passion of Mr. Diamond, Lazare Kaplan

Born in 1883 as the third-generation of a family of jewelers, Lazare Kaplan was recognized as an outstanding diamond cutter at a young age in Antwerp, Belgium, and became independent at age 20. He later moved his base to New York, USA, dedicating his life to the pursuit of 'The World’s Most Beautiful Diamond®'. In 1919, based on the theories of his cousin, mathematician Marcel Tolkowsky, he practically achieved the 'Ideal Make'—a perfect proportion that allows diamonds to sparkle in seven colors—through precise cutting. This ideal and luxurious cutting technique remains the strictly upheld brand identity of Lazare Diamond over a century later. In 1935, he was entrusted by renowned jeweler Harry Winston to cut the massive 726-carat Jonker Diamond, completing this remarkable feat over one year. Already known as the 'Magician of Cutting' at the time, Lazare Kaplan also contributed to the proper evaluation of diamond beauty and value, talent development, and technological innovation. He advocated the importance of cutting in creating diamond brilliance and played a major role in establishing the 4Cs standard at American gemological institutions. Thanks to his noble aesthetic vision and numerous achievements, Lazare Kaplan became a legend and is still celebrated today as 'Mr. Diamond'.
