Brilliant cluster of iridescent Covellite on Quartz matrix! Also with Pyrite, these free standing blades are in excellent condition with most being complete. Some show evidence of having terminated into matrix which created a wider edge with just a touch of dusting. The largest Covellite crystal at top measures just over 1 cm in size. The blend of blues, purples, and reds are excellent with this fine miniature! From the Leonard Mine, Butte, Silver Bow County, Montana.
