An excellent, rich specimen rich in light green crystals of Vajdakite showing good crystals in open vugs.

Vajdakite (IMA No. 1998–031) is named after Josef Vajdak of Pequa Rare Minerals, Massapequa, New York, USA, in recognition of his significant contributions to mineralogical research on the Jáchymov ore district. Vajdakite is a monoclinic molybdenum bearing arsenide which occurs in veins associated with arsenic, scorodite, annabergite, nickelskutterudite, löllingite, and köttigite.
