A remarkable specimen featuring unusually translucent and sharp hexagonal crystals to 4cm erupting from massive platy brucite...such large freestanding crystals are exceedingly uncommon! Once cleaned it surprised me with a great translucency and luster that had been hidden under 100 years of grime. This specimen is a monster for the locality and would be priced much higher if not for some contacting on the right side of the large centeral crystals. True, that detracts a little bit, but not enough to make this any less significant though it brings the price down to earth. Because of the widely known association between this now-defunct but classic locality and noted collector William Jefferis who was the major collector of this material in the mid to late 1800's, these specimens often are dear to collectors of antique US minerals and localities. 8 x 4 x 3cm

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.
