Graff Diamonds has taken the wraps off the 302.37 ct. Graff Lesedi La Rona, the largest gem produced from the record-breaking 1,109 ct. rough that sparked worldwide headlines when it was discovered at a Botswana mine.
The emerald cut has received a D color grade from the Gemological Institute of America (GIA), as well as the GIA’s “highest clarity” grade, Graff says. While that presumably means it received a grade of flawless, a company spokesperson beat back repeated inquiries about its clarity.
“I can disclose it is the largest highest-color, highest-clarity diamond ever graded by the GIA,” the spokesperson said.
It is also considered the world’s largest square emerald cut.
