This excellent specimen feature superbly defined radiant, cherry-red crystals of silver-sulfosalt Proustite from one of the great European locales, though we see few on the market. This specimen is relatively elegant and sparkling, rather than the usual dull lumpy mass of dark Proustite. It has been kept in a box, or in the dark, for most of its lifetime since being mined - Proustite does slowly go darker over time in light. Most of the crystal terminations seem to be terminated in a nice way. For overall aesthetics, colour, and size, this is a great mini.
