Premier Rose Diamond

In March 1978 the Premier Mine in South Africa, the mine that produced the 3,106-carat Cullinan Diamond, yielded a triangular-shaped cleavage diamond of the finest color, weighing 353.9 carats.

For security reasons, news of the finding of the diamond was not released for two months. After it had been disclosed, the press quickly began speculating about possible destinations for the eventual polished gem(s), with Prince Rainier of Monaco and Emperor Bokassa of the Central African Empire being two of the most notorious names bandied about. In the end it was purchased by the Johannesburg (South Africa) firm Mouw Diamond Cutting Works, in partnership with William Goldberg of New York City, New York.

The rough diamond was marked for bisection by Rose Mouw, the spouse of Jacob Mouw, the founder of Mouw Diamond Cutting, and produced three major polished gems. The largest, named Premier Rose for its mine of origin and Rose Mouw, is a pear shape weighing 137.02 carats, cut with 189 facets. The Gemological Institute of America gave it a D-color and Flawless clarity grade, making it at the time the largest stone of this caliber to have been certified by the GIA. It is also the fifth largest pear-shaped diamond, by weight, in existence. The other two gems in the collection are the 31.48-carat Little Rose and 2.11-carat Baby Rose.
