This thumbnail specimen consists of a cluster of stacked hexagonal tabular crystals. I hesitate to call it an "iron rose", as the formation just doesn't bring that to mind. Some of the platelets are damaged and incomplete, but most are intact and show excellent form and a good hexaonal outline. They have the standard dark-gray coloration and a dull metallic luster along their edges, whereas their faces show a much brighter metallic shine. It is a pretty piece that I might just have to purchase for myself if nobody else does.
