“When did you last see a transparent, lustrous, lilac colored scalenohedron of calcite, from Missouri, or, from anywhere? A bruised termination is the only drawback to this otherwise remarkable specimen (very slight cleaves a tthe tip, only noticeable up close and typical in any case of old tristate material). These lavender calcites came from one small mine, near Joplin, in the 1940s. MOST of them were rhombohedral, and this is the only large and fine scalenohedral example I have ever seen. The color is immediately recognizable and is truly unique for calcite, and for the district. I am not aware of any more having been found elsewhere outside this small mine, and it was closed by the mid-1950s. Truly a midwest rarity! 9 x 7 x 4.3 cm ”
