Brucite from Wood’s Chrome Mine, Lancaster County, Pennsylvania, USA
Wood’s Chrome Mine is the classic American locality for crystallized brucite. Its best specimens are not merely “old Pennsylvania” curiosities; they are benchmark brucites: pale, lustrous, translucent plates and rounded aggregates that show the mineral in a sculptural, collectable form rather than as anonymous foliated masses. The finest pieces display stacked pseudohexagonal blades, pearly to waxy faces, and a subdued color range from colorless and white through grayish and pale yellow-green to the soft green tones most prized from the locality.
