A sharply crystallized rosette, or spherical aggregate rather, of translucent brucite from this important East Coast locality. It was almost certainly collected during the mid to late 1800s heyday here. Fine miniatures of this material, that actually have some aesthetics, are VER rare and hard to get ahold of. I have had bigger pieces, pricier pieces, bigger crystals, but never such a nice showy specimen for the size.

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.
