Hyalophan – Zagradski, Busovaca, Bosnia and Herzegovina
 Former collection of Dr. Walter Kühnel via Maresa Gößwein, 16.11.1996
 One of the rare hyalophane specimens from the site in Herzegovina, Bosnia, famous for its hyalophane minerals. The crystals have a particularly sharp edge. Most of the crystals found have crystallized as floats. Therefore, matrix specimens are extremely rare.
 Very rare classic from the 1980s.
