Thumbnail, 1.5 x 1.0 x 0.4 cm
A fairly rich specimen of the extremely rare mineral species named after noted Franklin area collector Richard Hauck, consisting of several dozen eye-visible microcrystals on contrasting matrix, with minor Pyrochroite (Black) in association. Almost seventy new mineral species have been described from the unique Franklin area, and this is one that remains unique to Sterling Hill, to my knowledge. This particular hauckite was sold by the famous Franklin dealer Ewald Gerstmann and has been in a private East Coast collection until now. It would be considered quite a good specimen! 1100 stope, 900 Level, Sterling Mine, Ogdensburg, Sussex County, New Jersey. 1.5 x 1 x 0.4 cm
