Named for the mineral collector who provided and studied the specimens, Pierluigi Ambrino. Ambrinoite is a rare mineral that is found only at the type locality in a Triassic evaporitic formation of gypsum near Signols in Piedmont, Italy. This sulfosalt is associated with sulfur and orpiment and occurs with galkhaite, stibnite, and enargite. It appears as red, resinous aggregates of tabular crystals.

Named to honor mine owner James Ames. Amesite is a rare mineral that is the result of the low-grade metamorphism of aluminum and magnesium rich rocks.

Assocaited minerals include vesuvianite, chlorite, magnetite, rutile, diaspore, grossular, calcite, diopside, and clinozoisite.
