Graff - ‘Lesedi La Rona’

Graff presented 'Lesedi La Rona' in the first quarter of this year. It is the largest cut diamond in the world. But let's be right, it happened at the Conde Nast conference in Cape Town, South Africa. Here, Laurence Graff revealed a record-breaking diamond. The 302.37 carats 'Graff Lesedi La Rona' has been officially recognized as a hollow diamond with the highest color and highest purity. GIA is looking forward to seeing it as the diamond that is the first such parameter ever to be acquired as the largest diamond in the world. 

This diamond was found in the mine of the Lucara Karowa mine in Botswana It was the largest unworked high-quality diamond that has been discovered for over 100 years and was only the second largest ever found. Its parameters were 1,109-carat Lesedi La Rona rough diamond 

With such a large diamond, new challenges have emerged for the company. Graff’s expert gemmologists had never analyzed such an enormous stone.  A diamond of this size is so rare that the Lesedi La Rona was too large for Graff’s equipment. The solution? A custom-built scanner was created specifically for the diamond. Using this imaging technology, Graff’s gemmologists explored the diamond, were able to identify the imperfections within the rough, and then plot which cuts would yield the largest and highest clarity diamonds based on this information.
