The historic town of Cullinan is found less than an hour’s drive from Johannesburg International Airport in South Africa. This famous diamond mine and village is a great overnight diversion for travelers arriving or departing via Johannesburg. It is an interesting introduction to the country and a completely different experience when compared to the wildlife or city attractions.
A story of the mine's discovery
A story passed down from generation to generation, tells how Tom Cullinan had to use some creativity to identify the rich diamond pipe that lead to the Cullinan Diamond Mine’s birth.
He heard that people were finding diamonds in the rivers of the area and tracked the rivers back to what he thought was the source of the diamonds. However, this source was located on a privately owned farm and when Tom approached the farmer, the farmer was quite hostile and refused any prospecting to be done on his land.
With the help of some colleagues Tom Cullinan placed the carcass of a cow on the farmers land. When told that a sick cow had died on his farm, the farmer agreed to allow Tom and his friends to bury the cow immediately to avoid the spread of disease.
Tom set out to the farm and dug one almighty hole, much larger than one needed to bury a cow, but enough to investigate the soil deep in the earth. They struck a line of blue soil confirming his suspicion of a diamond pipe on the farm.
Tom approached the farmer offering to buy the farm but was met with much resistance. It was only after the farmer’s family ran into financial trouble that they agreed to sell and mining was started.
