Just at this moment the discovery of diamonds effected a revolution in South African affairs. As this incident is variously described by many writers, and as its importance is so great from an historical point of view, I propose to pin my faith upon the record given by Dr. George M. Theal. His position as a civil servant and Historiographer to the Cape Government would, perhaps, lay the most impartial of historians open to occasional allegations of favoritism in dealing with annals so permeated with Dutch and English rivalry as are those of South Africa. But there can be no question as to his accuracy in treating of such questions of fact as this.[1] He states that: "One day, in 1867, a child on a farm in the north of Cape Colony was observed to be playing with a remarkably brilliant pebble, which a trader, to whom it was shown as a curiosity, suspected to be a gem of value. It was sent for examination to a qualified person in Grahamstown, who reported that it was a diamond of twenty-one carats weight and that its value was £500. Search was immediately commenced in the neighborhood by several persons in odd hours, and soon another, though much smaller, was found. Then a third was picked up on the bank of the Vaal River, and attention was directed to that locality. During 1868 several were found, though as yet no one was applying himself solely to looking for them. In March, 1869, the 'Star of South Africa' was obtained from a Korana Hottentot, who had been in possession of it for a long time without the least idea of its value except as a powerful charm. It was a magnificent brilliant of eighty-three carats weight when uncut, and was readily sold for £11,000." [1] The Story of the Nations Series. _South Africa_, p. 322.
