Datolite is a hydrous calcium borate-silicate. Klaproth (1806) named datolite using the Greek dateisthai to divide, for the divided and granular nature of type material. According to the 1995 Handbook of Mineralogy, the largest known datolite crystals come from Westfield, Massachusetts, and Charcas, Mexico. Dal'negorsk also produces large crystals.

This is a completely crystallized plate of datolite, with individuals to 4.5 cm across. This piece appears to have detached from the vein wall and recrystallized. Discontinuous drusy quartz partly coats the datolite crystals. Attractive. Found 2020.
