Name:
Named in honour of Victor Victorovich Sharygin (b.1964) from the Sobolev Institute of Geology and Mineralogy, Novosibirsk, Russia. He is a mineralogist, and expert on alkaline and pyrometamorphic rocks. He worked on xenolith specimens with sharyginite from Eifel and published some preliminary data on the mineral.
The Fe analogue of shulamitite.

The crystal structure of sharyginite is closely related to that of shulamitite.
