The largest synthetic diamond in the world comes from Augsburg
Augsburg/MSch/KPP - After 25 years of intensive research, physicists at the University of Augsburg have succeeded in the synthesis of a single crystal diamond disc, which even compares favourably to the Queen’s crown jewels when it comes to sample area. In the renowned magazine Scientific Report they reported on their spectacular results and the long journey that has led to this success.

One remarkable aspect of their technique is that they can grow on a treated iridium surface to achieve single crystal diamond growth. Previously, specially oriented and polished diamond was required for homoepitaxial growth.
