Since 1903, Lazare Kaplan International Inc. 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 brand its uniquely brilliant diamonds. The Lazare Diamond is the original ideal cut diamond. Using an exacting mathematical formula, our master cutters create each Lazare Diamond with astounding precision. The result: unparalleled beauty and grace, maximizing the coveted diamond characteristics of brilliance, scintillation and fire. In addition to having the world’s most beautiful diamonds, Lazare also has a beautiful selection of engagement ring settings. Below is just a preview of the mountings designed by Lazare.
