A crudely formed copper crystal with very minor prehnite has become the matrix for two very SHARP, feather-like, aesthetic growths of native silver to 2.5 cm in length. This silver growth is reminiscent of classic specimens from this Kearsarge Amygdaloidal Lode. This combination of copper and silver, while not uncommon, makes for a superb minature because it IS uncommon in aesthetic specimens with well crystallized silver atop. Usually, the mixes are just lumps. This one is stunning!
