Radcliffe and Bailey (1972) state the following about the Hogg Mine:

β€œThe body lies in the southwestern part of the Georgia Piedmont close to the Alabama State Line. The pegmatite is a typical lensoidal graphic granite pegmatite separated from a rose quartz core by a narrow replacement zone characterized by A-type muscovite and beryl. Crystals of beryl weighing several hundreds of pounds are reported to have been collected from the property."

β€œThe beryl occurs in three distinct types: crystals elongated parallel to c, crystals flattened on the basal pinacoid, and masses of aquamarine up to 6 inches in dimension which are invariably fractured. This fracturing is of a regional nature and affects all minerals in the pegmatite. The fractures in the aquamarine are filled with small crystals (up to 1 mm) of transparent beryl set in a friable matrix of white beryl. These latter probably represent a second generation of beryl emplaced in the original crystal of aquamarine. This is the first reported occurrence of this phenomenon.”

This mine is now a fee dig for beryl (aquamarine), tourmaline, and rose quartz.
