Specialists of the Yakutsk Diamond Trade Enterprise discovered this unusual diamond during a sorting process. They handed it over to the Research and Development Geological Enterprise of ALROSA. There it was studied using several methods, including Raman and infrared spectroscopies, as well as X-ray microtomography.

Based on the results of the study, the scientists made a hypothesis about how the crystal was formed. According to them, there was an internal diamond at first, and the external one was formed during the subsequent stages of growth./ alrosa
