United States. In 1965, the Chrysanthemum was named a winner of one of the Diamonds International Awards and was placed on display in the Rand Easter Festival in Johannesburg, South Africa. It was one of five featured stones brought out to celebrate the 100th year of discovery of diamonds in the famous Kimberley mines. Julius Cohen initially sold the diamond to an unknown buyer. The diamond returned to the world stage in 2003 when the jeweler to the English royal family, Garrard & Co, purchased the stone. The Great Chrysanthemum was featured prominently in Garrard's 2007 catalogue that also featured Princess Diana's heirloom engagement ring. Since then, it has gone on display once again, most notably in recent years by such high profile personalities as filmmaker and former First Lady of San Francisco, Jennifer Siebel Newsom, who wore the diamond to a “Women of Power” event in 2008. Garrard reportedly sold the Great Chrysanthemum to a foreign anonymous buyer. See also List of diamonds References Individual diamonds Diamonds originating in South Africa 1963 in South Africa
