A superb analcime, considered by many copper country aficionados we have spoken to to be among the best examples of this old material from Copper Country due to size, color, matrix contrast, and unusual separation. Largest crystal is 3.5 cm. PRISTINE! Purchased from Don Olson, private collection, 2/14/2018 by Sean Finneson. Published in Mineral Collections in the Pacific Northwest (Mineralogical Record, Sept. 2019 -Scovil photo at end of our own photos). Included in Sean Finneson Copper collection as exhibited in Tucson 2022. Also pictured in the Mineralogical Record's issue on Michigan Copper (Jan. - Feb. 2023, pg. 129); where it was recognized by author Chris Stefano as one of if not the finest Analcimes to come out of the Keweenaw Peninsula.
