Nobleite is a rare calcium borate, isostructural with tunellite. Erd et al. (1961) named the mineral after Dr. Levi Noble (1882-1965), geologist at the United States Geological Survey.

Nobleite here forms platy colorless crystals to 2 mm completing covering an earlier generation of colemanite. This is a rich example completely covered in this rare borate. A label from Callahan's Gems and Minerals accompanies the specimen.
