In 1919, Marcel Tolkowsky, a cousin of Lazare Kaplan, developed a complex mathematical formula for cutting a diamond to its precise angles and proportions. To Lazare Kaplan, the formula came to define the "ideal-cut" which maximizes a diamond’s beauty. There is no denying that other diamond cutters have applied the formula to produce ideal-cut diamonds, but only LAZARE Diamonds® are cut consistently to the highest and most stringent standard without exception. Only 1% to 2% of LKI production meets the quality and uncompromising ideal-cut standards deserving of LAZARE Diamonds®.
Every LAZARE® diamond is ideal-cut. When a diamond is ideally cut, light rays from all sides are bent towards the center of the diamond and are reflected back through the top in a blaze of light. If a diamond is not ideally cut, light will “leak out” through the sides or bottom of the diamond. The ideal-cut guarantees you a spectacular balance of brilliance, scintillation and fire.
Every LAZARE® diamond is cut for maximum beauty, not weight.
The ideal cut is a mathematical formula for cutting diamonds to precise angles and proportions which guarantees you a spectacular balance of brilliance, scintillation and fire.
See for yourself by asking your jeweler to show you the difference between an ideal cut LAZARE® diamond and other diamonds. When you see it, you just know.
