Tourmaline Turns 200 commemorates the bicentennial of the discovery of the Maine state mineral, tourmaline, in the fall of 1820.
Tourmaline (elbaite) is now known from more than 60 locations in Maine and gems have been faceted from at least a dozen of them. The exhibition combines specimens showing the range of colors, forms, species, and occurrences of Maine tourmaline with items from MMGM’s archival and library collections.
On view in the Discovery Gallery now through Fall 2021. Happy Birthday Tourmaline!
