Senarmontite (Sénarmontite) - Sold


Dana (1851) named sénarmontite in honor of Henri Hureau de Sénarmont (1808-1862), a French mineralogist who first noted the species (Sénarmont, 1851). Senarmontite is a cubic oxide of antimony. Crystals are typically octahedral, in this case to 1.0 cm on edge. This is a tight aggregate of crystals, unfortunately bruised, but nevertheless large for the species. Likely found on the mine dumps in the 1970s, this specimen has darkened to a light gray color. When fresh, the species is lustrous and colorless.
