The Eureka was discovered per chance by a 15-year-old boy, Erasmus Jacobs, on the south bank of the Orange River near Hopetown, Kimberley in 1867 and later handed it to his neighbour, farmer Schalk van Niekerk, who was a collector of unusual stones. Van Niekerk entrusted the stone to John O’Reilly, a travelling peddler, who sent it in an unsealed envelope to Dr. W.G. Atherstone of Grahamstown, one of the few people who knew anything about minerals and gems. Dr. Atherstone identified the stone as a 21.25ct brownish-yellow diamond and was sold to Sir Phillip Wodehouse for GBP 1,500.
