The rough diamond was cut into several polished gems. The largest cut gem is named Cullinan I or the Great Star of Africa, and at 530.4 carats (106.08 g) is the largest polished white diamond in the world. It was the largest polished diamond of any color until the 1985 discovery of the Golden Jubilee Diamond, 545.67 carats (109.134 g), also from the Premier Mine. Cullinan I is now mounted in the head of the Sceptre with the Cross. The second-largest gem from the Cullinan stone, Cullinan II or the Second Star of Africa, at 317.4 carats (63.48 g), is the fourth-largest polished diamond in the world. Both gems are in the Crown Jewels of the United Kingdom.

“Today in History” on The Pandora Society dot com is primarily focused on Victorian and Edwardian history and does not always have a direct connection to Steampunk, Dieselpunk, or whatever punk; in fact it rarely does, but it is our hope that in sharing these historical events they might serve as some inspiration to the writers in our community to create potential alternative history stories which we look forward to reading 🙂
