Watermelon tourmaline is a variety of concentrically color-zoned tourmaline with red interiors and green exteriors and is distinct from longitudinal bi-color or polychrome zonation. The name was coined by George Robeley Howe [1860-1950] of Norway, Maine, USA. The name was first used in a Lewiston, Maine newspaper account in 1910 when describing specimens from the Havey Quarry in Poland, Maine, USA. The name was used in an international publication, Mineral Resources of the United States, by Douglas B. Sterrett in 1911.
