An EXCELLENT, undamaged cluster of lustrous, off-white to tan, trapezohedral Analcime crystals intergrown with super sharp Copper crystals. From the famous Keweenaw Peninsula of Michigan, this superb thumbnail actually can be displayed from either side. One way, you can highlight the large, very fine Analcime, or from the reverse side you can emphasize the Copper crystals. Either way, the aesthetics of this top-notch combination piece are outstanding and it is competitive-level in quality. I have not seen such a dominant analcime with copper, in a fine thumbnail specimen of this caliber before. Ex Robert Randall collection (he was a competitive exhibitor in the 1970s and 1980s).
