Mineral specimens are rare indeed from the ancient emery mines at Naxos Island, Greece, mined for emery by the Classical Greeks. The vuggy matrix is probably metabauxite. A really pretty, 1.7 cm radial, starburst-like spray of lustrous, colorless aragonite prisms rests above a euhedral, glassy, tabular, 1.3 cm, partially coated anorthite crystal. This old-time specimen certainly dates to the 19th Century and is from the Philadelphia Academy of Sciences Collection.
