Very sharp, typically bladed and disclike crystals of this rarely crystallized species, from THE classic locality in the US. This was not the first locality, but it has remained the best in the USA for sharp crystals and they are quite different in habit from the fine brucite found at a very few other lcoales (Kazakhstan, and South Africa) today. This piece has large, translucent crystals to 2 cm across, and combined with the overall size of the specimen is thus fairly significant. Ex. George Loud collection and University of Chicago Museum collection

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.
