This large hand specimen consists of part of a crust of heavily-intergrown Amethysts. These crystals are generally in good condition and reach lengths of 2.2" (5.6 cm) or more. However, all but 0.5-1.0" (1.3-2.5 cm) of their lengths are intergrown. Each crystal is layered, also with a section of dark purple Amethyst that is covered by a much paler violet layer. This pale layer shows the exposed terminations, which are partly covered by crustas of crystalline calcite that are all aligned in one direction.
