Patches of non-fractured surface on the pavilion showed the normal transparency of diamond, causing the radiation staining to stand out in relief. Yet closer examination revealed that the fractures were surrounded by dark brown radiation stains. Upon initial examination, the stone was noted to be covered in large, deeply penetrating fractures therefore, high-pressure, low-temperature treatment was suspected.
