Glassy, transparent exceptionally sharp fluorite 'spear point' with no point of attachment and well crystallized on all sides. These specimens are highly characteristic of the Minerva #1 complex and certainly the finest examples have been collected there. This specimen is from the Cross-Cut Orebody and collected from mining in one of the highly petroliferous areas that enabled the high-quality luster seen here. Contemporaneous barite and fluorite precipitation interfered with normal fluorite crystallized and caused the fluorite 'spike' and 'nail head': late-stage barite dissolution revealed the process. Excellent miniature mined ca. 1991-1992. Tolonen Collection.
