This is the second of two superb, sharp, lustrous specimens of antique pyrite from the famous French Creek Mining area,. Both are from the collection of ER Chadbourn, early 1900s, through Phil Scalisi's collection rife with US classics, and recently belonging to another US East Coast collector. This piece has sharp crystals, somewhat curving, upon a knoll of matrix. It is pristine and shows no sign of decrepitating "pyrite disease."
