Graff Lesedi La Rona Diamond

Luxury jeweler, Graff, has unveiled its latest, and perhaps its greatest, big diamond creation, the “Graff Lesedi La Rona,” a 302.37-carat D-color, high-clarity stone that is being lauded as the world’s largest square emerald cut diamond. The London-based company also says it is the “largest highest clarity, highest color diamond ever graded by the GIA.”

When the 1,109-carat Lesedi La Rona was discovered in 2015 in Botswana, it made history as the world’s second largest gem-quality diamond — surpassed only by the 3,106-carat Cullinan.With hundreds of hours needed just to polish the table facet, elaborating on the 18-month-long cutting and polishing process, which included nearly a year of analysis by master craftsmen and gemologists in Antwerp, Belgium. The Graff Lesedi La Rona is an exceptional diamond with an exceptional cut and exceptional proportions, earning its place in history as the largest and finest of its kind in the world.
