 | The Blue Moon was cut from a 29.62-carat rough diamond unearthed at the Cullinan mine in January. The mine is known for producing blue diamonds, but these gems still account for less than 0.1 percent of its total diamond output.
The Blue Moon diamond drew widespread media attention when the discovery of the 29.62 ct rough at the Cullinan mine was announced in January 2014. This mine, formerly known as the Premier, is also the source of the historic Cullinan diamond, as well as two other important blue diamonds: the Smithsonian Institution’s Blue Heart, a 30.62 ct Fancy Deep blue gem discovered in 1908, and the 27.64 ct Fancy Vivid blue Heart of Eternity, unveiled by Steinmetz in 2000. |
