Carbonado typical gem diamonds. Lead isotope analyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks. Mineral grains included within diamonds have been studied extensively for clues to diamond origin. Some typical diamonds contain inclusions of common mantle minerals such as pyrope and forsterite, but such mantle minerals have not been observed in carbonado. In contrast, some carbonados do contain inclusions of minerals characteristic of the Earth's crust: these inclusions do not necessarily establish formation of the diamonds in the crust, however, because while these obvious crystal inclusions occur
This Is What Rock n' Roll Looks Like Black's choreography as "racy," later complimenting Porcelain Black on her "two-toned, Cruella De Vil-inspired coiffure." Porcelain Black walked down the runway in a camouflage corset designed by Falguni and Shane Peacock at the 2012 Spring Fashion Week, as her song played in the background. Her appearance there was used to promote the single. "This Is What Rock n' Roll Looks Like" appeared in the tenth episode of the eighth season of Beavis and Butthead.
