- Berthierite, Stibnite

- Bohutin, Pribram, Central Bohemia Region, Bohemia (Bohmen; Boehmen), Czech Republic
This is a heavy specimen of mixed Pribram ores with embedded berthierite crystals, which are rare for the locality. This long resided in his personal reference collection of Czech classics of Josef Vajdak, a rare species mineral dealer from New York, now 80 years of age. Josef claims to have done research indicating that these were found in the 1880s, and considered this a very good example of this rarity for the locale. Note the minor stibnite in association, also a rarity for the locale.
