At least 20 Goshenite crystals are clustered together or scattered individually on the base of this large hand specimen. The largest of these crystals has a length of 1.0" (2.5 cm) and a diameter of about 0.8" (2.0 cm), whereas most of the others have dimensions that are half of those, or less. Oddly, the largest crystal (which is also the most exposed) is also in the best condition- most of the smaller ones are also intact, but many are damaged, and some are incomplete or very badly broken. Their hexagonal prismatic form is very warped, with rounded faces and curved edges- the only crystal that has a definite and complete hexagonal outline is the largest one. Others show the occasional flat face, but are very much incomplete. The side of the flat piece opposite of that containing the largest crystal has a mass of very warped, intergrown crystals that show no almost crystal form at all, and possess no crystal faces that are visible to the naked eye. However, one can see crystalline tendencies with magnification. All of these crystals are colorless, transparent, and where visible, quite clear. The base on which they rest is made up primarily of warped, crystalline albite and a substantial amount what appears to be actinolite, most of which has very good monoclinic prismatic form. Some of it, however, has separated into a fibrous habit.
