Celebrating The Big Find (Fifty Years Later) at the Tucson Gem and Mineral Show.

Tourmaline mining in Maine began with the first find of gem-quality tourmaline at Mt. Mica in 1820 and continues today at numerous localities. In October 1972, on the eastern slopes of Plumbago Mountain in Newry, Maine, the largest single discovery of gem-quality tourmaline in North America was unearthed - more than a ton in all. Mt. Mica, the Havey quarry, and the quarries at Mt. Marie are all notable contemporary locations for gem tourmaline in Maine. [Extracted from the article]
