Copper Falls Mine, Copper Falls, Eagle Harbor Township, Keweenaw County, Michigan, USA
Locality type:Mine
Classification
Species:Analcime
Formula:Na(AlSi2O6) · H2O
Comments:When they are associated with good copper crystals they become objects to lust after. I am sure that the best of them would bring well over a thousand dollars but without the copper association these analcimes would probably not even make this list of notable localities. Also as rare pseudomorphs after feldspar(?).
Habit:Trapezohedra to 2.5cm in diameter
Colour:reddish
Quality for species:Excellent - world class for species or very significant. (!!)
Confirmation
Validity:Believed Valid
Associated Minerals:
