The Kruchev dol Mine is producing some of the finest sulfides ever seen from the district. It now appears that the great stopes where these were coming from are playing out. This specimen is one of the very bright sphalerites that was mined towards the end of 2007. In actuality, great sphalerites are more difficult to obtain than galenas which may reflect the lack of fine crystallized specimens of zinc or perhaps it may be because galenas are more in demand but the former is probably the case. Sharp and clean and without damage. 5 x 9 x 9.5 cm.
