The Aurora Collection is coming to London. The London Natural History Museum has announced that a set of 296 naturally colored diamonds has been lent for display by diamond collectors Alan Bronstein and Harry Rodman.
Composed of a total of 267.45 carats of exceptionally rare stones, including the 12 color varieties from emerald green to blood red, the Aurora Collection is on display in The Vault, the museum’s newest permanent gallery. It was first displayed in Europe in 2005 as part of the Natural History Museum’s Diamonds exhibition.
Fancy colored diamonds are relatively rare. Only one in every 10,000 gem quality diamond is colored, and the color is a result of tiny amounts of non-carbon elements, or from atomic scale defects, in the diamond structure, the museum release stated.
“Each colored diamond tells its own story, giving us insight not only into its formation, but also to the deep earth processes that took place when the gem was formed,” said Alan Hart, curator of minerals at the Natural History Museum.
“For example, yellow diamonds are due to the presence of nitrogen in the structure and green diamonds owe their color to natural radiation damage. It’s an amazing opportunity to be able to display this unique collection of exceptionally rare gems at the Museum,” he concluded.
