A fine botryoidal crust of yellowish-white Gibbsite on Limonite ore. From the famed Oren Root collection (with label) which was transferred to Hamilton College in 1835. The Root collection was at that time the finest in the United Staes. This was a new specie named in 1822 in honor of Colonel George Gibbs who was also an important early American mineral collector. This is a very early piece from the type locale, when first found it was misidentified as Wavellite. The specimen left Hamilton College to the NY State Museum collection then to Don Potter and later to Dr. Steven Chamberlain, then to Carter Rich. A long history indeed. Good fluorescence as well, with green and yellow zones LW and midwave shows green to bluish purple and yellow zones.
