The Big Find: The Legend Continues

In October of 1972, the largest single discovery of gem-quality tourmaline was found in the hills of Western Maine. To celebrate this dazzling find, the MMGM commissioned 12 artists to create extraordinary, one-of-a-kind pieces utilizing gemstone from The Big Find. These 12 pieces commemorate the unbelievable nature of the exquisite discovery, and showcase the dynamic beauty of modern-day craft and artistry. The pieces are currently on display in the museum store.
