Name:
Named in honor of Priscilla Croswell Perkins Grew (b. 1940, Glens Falls, New York, USA) geologist and professor at University of Nebraska–Lincoln, for her work showing oscillatory Mn zoning in eclogite garnet. She was also Director of the University of Nebraska State Museum of Natural History, and held various government positions including Director of the Minnesota Geological Survey. The unrelated mineral edgrewite is named after her husband.
A purely aluminate garnet. Unique combination of elements.
