This small thumbnail specimen consists of a single pseudocubic Boleite crystal. This crystal is the largest that I have yet seen in my travels, and though it shows some noticeable damage, it is still in good condition. Its form appears to be cubic, but many sources say that this mineral is tetragonal in nature. Its edges are well-defined and its faces are clean, possessing a bright pearly luster. The size of the crystal and its deep blue coloration prevent all but a faint translucence from showing around its edges in strong light. There is a triangular imprint on one face where another crystal partly intersected this one. There is no host rock present, and the specimen is affixed inside a plastic specimen box with an adhesive putty.
