The Jonker

The Jonker diamond was found at the Elandsfontein mine in South Africa by Johannes Jacobus Jonker on 17 January 1934. The diamond was 726 carats, which at the time was the fourth largest uncut gem ever found. The diamond was found 5 km away from the largest diamond ever found, the Cullinan Diamond. There is speculation that the Jonker may have originally been part of the Cullinan crystal, as both crystals had cleaved faces which seemed to match up perfectly.
