Name:
Named by Marek A. Zakrzewski in 1985 in honor of Stanisław Jaskólski (28 September 1896, Lviv, Ukraine - 4 August 1981, Kraków, Poland), Polish mineralogist and professor at Akademia Górniczo-Hutnicza in Kraków, Poland. He developed ore microscopy in Poland.
Silvery white metallic masses with no apparent cleavage. The breakage surface may look somewhat granular. Compare the chemically similar tintinaite.
