This is a cut and microprobed specimen from the stock of Dr. Jaroslv Hyrsl. The Berryite can be seen as the black, slender blades. The Pavonite crystals are also the blakes blades so they cannot be distinguished visually. Aikinite is also present which further complicates the issue. Both Berryite and Pavonite are rare silver-bismuth sulfides.
