Lazare Diamond Collection

Lazare Diamond Collection


Founded in 1903, Lazare Kaplan International Inc. has an illustrious history.  Building on tradition and a commitment to excellence, Lazare Kaplan has been the leader in industry innovation: the first to cut diamonds to ideal proportions, the first to laser inscribe diamonds, and the first to offer its uniquely brilliant diamond as a brand.

 The Company’s founder Lazare Kaplan once said, “I am passionate about cutting each diamond as beautifully as possible.”  Today the Company remains dedicated to cutting the world’s most beautiful diamonds, and continues to maintain the highest standards in the diamond industry, cutting every Lazare Diamond for optimal brilliance, scintillation and fire.  Lazare Kaplan International Inc. (LKI) has become the premier manufacturer and marketer of diamonds in the United States and is the world’s largest manufacturer of ideal cut diamonds.

In 1919, Marcel Tolkowsky, a cousin of Lazare Kaplan, developed a mathematical formula for cutting diamonds to precise angels and proportions to gain the optimum reflection and refraction of light.   Lazare Kaplan adopted this approach and the ideal cut theory was put into practice in 1919.

This method, based on a complex formula that measures with exacting precision a diamond’s many angels and proportions, produces a diamond that maximizes the characteristics that discerning consumers prize above all else: brilliance, sparkle and fire.

Because more of the stone must be cut away to achieve such perfection, the ideal cut is costlier than other manufacturing methods, and the manufacturing process demands a much higher level of skill on the part of the diamond cutters.  So rigorous and demanding is the process that less than 1 percent of the world’s diamonds are ideal cut.

 The ideal cut isn’t the only thing that differentiates Lazare Diamonds from other diamonds.  On the outer perimeter of each diamond, the Lazare logo and an identification number unique to that diamond are inscribed with a laser beam.  The logo serves as proof of authenticity, while the number is proof of ownership in case of loss or theft.   In the early 80′s LKI co-invented this process.  The inscription itself is invisible to the naked eye but can be viewed under 10-power magnification and does not affect the clarity grade of the diamond.

 This laser “signature” enables LKI to market its ideal cut diamonds as a unique, brand name product known as The Lazare Diamond.   Knowing that a particular brand name represents quality and is only available through the finest jewelers makes people feel more secure in their purchases.  By asking for Lazare Diamonds by name, consumers are assured of the finest quality and cut.
