Lazare Kaplan, one of the world’s foremost diamond cutters, envisioned diamonds that sparkle in seven colors, created by the Ideal Make. The praise for ‘The World’s Most Beautiful Diamond(R)’ and its rare brilliance is the pride of Lazare Diamond, known as one of the world’s three major cutter brands. Handling only conflict-free diamonds, its brilliance, polished by over 100 years of history and New York’s refined aesthetic, is chosen by those who know true quality.
Born in 1883 as the third generation of a gem merchant, Lazare Kaplan was recognized as an excellent diamond cutter at a young age in Antwerp, Belgium, and became independent at 20. He later moved to New York, USA, dedicating his life to the pursuit of ‘The World’s Most Beautiful Diamond(R)’. In 1919, based on the theory of his cousin, mathematician Marcel Tolkowsky, he practiced the ‘Ideal Make’ cut—a perfect proportion that makes diamonds sparkle in seven colors. This ideal and luxurious cutting remains the strict brand identity of Lazare Diamond even a century later. In 1935, he was entrusted by renowned jeweler Harry Winston with cutting the 726-carat Jonker diamond rough, achieving this feat over a year. Already called the ‘Magician of Cutting’, Lazare Kaplan also worked to legitimately evaluate diamond beauty and value, and contributed to human resource development and technology. He advocated the importance of cut in creating diamond brilliance and greatly contributed to establishing the 4Cs in US appraisal institutions. His noble aesthetic sense and numerous achievements leading the industry made Lazare Kaplan a legend, still praised as ‘Mr. Diamond’.
The unparalleled brilliance of ‘The World’s Most Beautiful Diamond(R)’ can only be achieved by excelling in every process. Lazare Diamond oversees everything from rough sourcing to cutting and polishing in-house—a globally rare diamond cutter brand. Rough diamonds are carefully selected, focusing on the naturally beautiful octahedron shape. They are cut into the luxurious ‘Ideal Make’ proportion, prioritizing brilliance over carat weight, and hand-polished by skilled craftsmen, bringing out overwhelming sparkle through dedication to every process. The laser engraving of ID numbers, now a proof of high-quality diamonds, is also a world-first technology co-developed by Lazare Diamond. Never compromising and always aiming higher—this is our pride inherited from founder Lazare Kaplan, and the truth of diamonds that sparkle in seven colors.
