Group of Quarries


Composed of three widely separated phosphate-bearing quarries. Oxford pegmatite field.

The first Rose Quartz crystals known in the world were found at Mount Mica Quarry about 1913-1915. The second locality for genuine rose quartz crystals in the world, the Dunton Gem Quarry, Newry, produced it's first crystals in 1927. A third world locality was discovered in 1942, at the Rose Quartz Crystal locality, by George Crooker. Rose Quartz crystals were found at the Nevel Quarry, Newry and in the Red Hill Quarry Group, Rumford, Maine in 1949. Rose Quartz crystals were not known in Brazil until 1958.
