A complete floater crystal with sharp terminations on each end. It features extreme elongation, not common to the other specimens. The core is transparent while the tips are included by a red mineral that we believe to be dendritic manganese. Collected in the summer of 2010. Analyzed by Dr. Robert Downs at the University of Arizona. 1.4 x 0.6 x 0.3 cm.
