This rare alteration product of millerite is found in geodes where joint fractures in the Harrodsburg Limestone cause localized weathering of the rock. The dolomite crystals adjacent to the green jamborite are lemon yellow. Specimen in the collection of, and collected by, the photographer Alan Goldstein. (Found March, 2004)
