As displayed, this specimen features a stunning gypsum crystal that looks like it is a parallelogram carved from glass. The crystal is perched on two disjointed shards of matrix, that stick out and give it more 3-dimensionality as a specimen. It is 11 cm from tip to perfect tip, and is so gemmy and clear that you think at first it might be a cleavage fragment (with the dull surfaces chipped off). But this is classic Naica material, just an exceptional example in how it displays. Comes with custom lucite base. Joe Budd photos. Ex Dalton and Consie Prince private collection, and probably obtained in the 1970s or 1980s
