Acanthite after Pyrargyrite

Acanthite is a silver sulfide, and pyrargyrite is a silver antimony sulfosalt. Kenngott (1855) named acanthite for its monoclinic habit using the Greek root acantha for thorns. Pyrargyrite takes its name from the Greek roots pyr for fire and argyros for silver.

This specimen is from the Kings' mine in Guanajuato (i.e. Reyes mine). Guanajuato has a long mining history dating back to the beginning of the 16th century. Crude hexagonal replacements to 15 mm tall and 8 mm across form a tight crystal cluster. Some white baryte is attached.
