Last week’s fact: The Lesotho diamond was found in 1967 and it remains the largest to be found by a woman. Mrs. Ernestine Ramaboa found the 601-carat rough diamond and walked for four days and nights to deliver it to a reputable diamond dealer. Except for the diamond Ernestine was penniless. The House of Harry Winston purchased the stone and broadcast the cleaving live on American television in 1968. Over the course of the next year eighteen gemstones were polished out of the stone. The Lesotho II is a 40-carat diamond that Onassis presented to Jacqueline Kennedy as an engagement gift.
The Lesotho I, recently came back to Harry Winston and is pictured here. It’s the big one at 71 carats.
