About GibbsiteHide

07618700014946370761552.jpg
George Gibbs
Formula:
Al(OH)3
Colour:
White, light gray, light green, reddish white; reddish yellow (impure); blue, turquoise; purple
Lustre:
Vitreous, Sub-Vitreous, Pearly, Dull, Earthy
Hardness:
2½ - 3
Specific Gravity:
2.38 - 2.42
Crystal System:
Monoclinic
Name:
Named by John Torrey in 1822 in honor of Colonel George Gibbs [January 7, 1777, Newport, RI - August 5, 1834, Sunswick Farms, NY], of Newport, Rhode Island, USA. Gibbs was a wealthy import merchant who was a geologist and mineralogist. He helped found early scientific societies for mineralogy and geology and wrote several scientific articles on geology, mineralogy, and agriculture. He amassed the finest mineral collection in the USA up to the 1810s and the collection was eventually purchased by Yale University where it was an excellent nucleus for its research and museum collection.
Commonly as nodular white masses in laterite.
