Thumbnail, 0.6 x 0.5 x 0.5 cm
A beautiful and lustrous, 6 mm, color-zoned boleite cube from the famous Amelia Mine at Boleo, Mexico. Most boleites are pretty much monochromatic. But this striking cube has royal-blue, almost electric-blue, edges and corners with centers being the more normal indigo or deep blue. Unusual, rare and highly representative, not withstanding one lightly bruised corner.
