Discovered in November 2015 at the Lucara Karowe mine in north-central Botswana, the hypnotic Lesedi La Rona weighing 1,109 carats (formerly known in media as Karowe AK6 or as Quad 1) is the largest gem quality rough diamond discovered in over 100 years.
In September 2017 following a successful negotiation with Lucara Diamond Corp, Laurence Graff, London-based jeweller, acquired the Lesedi La Rona.
Graff has now unveiled the largest square emerald-cut diamond in the world carved from the Lesedi La Rona.
The 302.37 carat Graff Lesedi La Rona is the largest highest colour, highest clarity diamond ever certified by the Gemological Institute of America (GIA), and the world’s largest square emerald cut diamond, expertly cut and polished by Graff’s world leading team of gemmologists and master polishers. This rare marvel required over 18 months of meticulous craftsmanship, and marks a historic moment in diamond history.
Lesedi La Rona means “Our Light” in Botswana’s Tswana language, and has been described as possessing exceptional quality and transparency, earning the full significance of its name.
Botswana, South Africa, and Namibia are the world’s three top producers of mined diamonds.
