Very sharp, textbook-quality 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 locales (Kazakhstan and South Africa) today. This piece has large, well-displayed crystals to 4 cm across, and is thus fairly significant.
