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. Happy Birthday Tourmaline!

The Big Find: A Legend Continues — Latest Updates

Call for Artists

In October of 1972, one of the largest and most significant gem tourmaline finds in North American history occurred in the mountains of western Maine. This discovery created – and still creates – ripples in the American gemstone industry.

The MMGM invites artists to tell the story of these gemstones – and their own story – through their artwork.
