This patent describes a process for separating diamondoid compounds from a solvent. It comprises providing a hydrocarbon solvent containing at least about 70 weight percent paraffins having at least 30 carbon atoms and less than about 5 weight percent aliphatics having less than about 30 carbon atoms; charging the diamondoid-containing hydrocarbon solvent to a separation stage under subatmospheric pressure and temperature within the range of from about 0 to about 150{degrees} C; and withdrawing a vapor stream enriched in diamondoids from the separation stage and condensing the vapor stream at a temperature from about {minus}80{degrees} C to about ambient in the absence of reflux to the separation stage.
