Tremolite is a calcium magnesium silicate and a member of the amphibole group (Hawthorne et al., 2012). The mineral name follows from the presumed type locality of Val Tremola in Switzerland, but the actual type locality is in an adjacent valley (Roth, 2006). Nominally, pure tremolite is colorless.

This is a curious lavender tremolite from New York, colored by minor Mn3+. The whole specimen consists of tremolite, mostly in a fine ground mass, with one prominent large crystal, 21 by 3 mm.
