A superb toenail/small miniature crystal, complete all around, lustrous, and totally transparent and translucent at the tip as well. This would be good if it were from Chanarcillo or Germany which produced a lot more proustites that were saved. For Jachymov, its nearly off the charts. Josef was a specialist in Pribram and Jachymov minerals in particular, and this came from his important private collection of minerals from these sites. Even though more rare than perhaps the Peruvian material, these do not go for the same premium price for some reason I cannot fathom to this day, so this is a chance to get a large, showy proustite in good shape tha tlooks like a 10k Chilean piece, for a "relative" bargain.
