Localities
At the Niederschlema-Alberoda U-Se-polymetallic deposit, Erzegebirge, Saxony, Germany, nevskite occurs either
as small rims between watkinsonite and
clausthalite, or as small grains associated with

in the body of clausthalite
(CM 43: 899-908.).
At the type locality, the Nevskoe W-Sn Deposit, Omsukchansky District, Magadan Oblast, Russia, nevskite occurs as
