In November 2003, De Beers announced that in celebration of the mine's Centenary, Premier mine would usher in the new era with a new name.
Premier mine, as it had been known for the past 100 years, became Cullinan Diamond mine.
The name change was first announced by General Manager of Cullinan Diamond mine, Hans Gastrow, as part of the mines' centenary celebrations.
The name change was aimed at recognising the brand that has become associated with Premier mine.
The name of the village of Cullinan had its beginnings in 1903 when it was named after the pioneer and entrepreneur Sir Thomas Cullinan.
It later came to the fore again in 1905, when the largest pure rough diamond was discovered and named the Cullinan Diamond.
The Cullinan Diamond played a significant role for Premier mine, and De Beers, when it received global recognition as a gem of the British Crown Jewels.
Over the year, the mine has attempted to stimulate economic activity in the area by maximising local recruitment, procurement and social investment.
In November 2007, De Beers sold Cullinan Diamond Mine to the black-empowered Petra Diamonds Cullinan Consortium (PDCC).
For Petra, this fits well with their strategy of adding more production assets to their business and allows them to acquire one of the world’s most famous diamond mines.
For employees, this brings in a partner with proven ability to sustain marginal operations and maximise the life of mine for the benefit of the entire Cullinan community.
For South Africa, this is consistent with Government aspirations for broadening BEE ownership and competition in a transformed diamond sector.
