Mineral Specimen #5312 Copper Crystrals with Casts after Analcime
Seneca Mine, Mohawk, Keweenaw Co., Michigan
Ex. A E. Seaman Museum
Copper crystals are accentuated with numerous casts after Analcime. The specimen does look like it was cleaned at one time many years ago and has now acquired a rich patina over the years.
Flaws: Nothing Appreciable
