In the summer of 1963, a 198.28-carat fancy brown diamond was found in the South African diamond fields. This unusual stone was purchased by Julius Cohen, New York City manufacturing jeweler, under whose direction it was fashioned by the firm of S & M Kaufman into a 104.15-carat pear shape. The stone has a total of 189 facets (67 on the crown, 65 on the girdle, and 57 on the pavilion) and measures 25mm wide, 39mm long, and 16.2mm deep. It is mounted as the central stone in a yellow gold necklace of 410 oval and marquise-shaped diamonds.
In the rought state, the diamond appeared to be a light honey color; after cutting, however, it proved to be a rich golden brown, with overtones of sienna and burnt orange, the warm colors of the brown chrysanthemum after which the stone was named.

The Great Chrysanthemum has been exhibited by several retail jewelers in the United States and was shown as a Diamonds International Awards winner in 1965. In the same year, it was displayed at the Rand Easter Festival in Johannesburg, South Africa. Julius Cohen later sold to it an unknown foreign buyer. Source: Diamonds – Famous, Notable and Unique
