Vitreous and pearly, radial groups and cross-sections of Esquireite composed of platy crystals to about 1mm.  It is most often found on cross cutting fractures in Sanbornite. Esquireite, in complete groups, are dull white spheroids, which can be seen on this specimen very well, though not photographed. By pricking one of the spheroids, the fresh cleavages of Esquiriete can be readily seen.
