Comment: ex H. Westenberger Collection This is a very interesting specimen, indeed. What really makes it interesting to me is that it displays a multitude of rhodochrosite generations or depositions in one specimen. The top layer which you see displayed in my first picture is made up of finely bladed pink rhodo xls measuring approximately 3mm in thickness. Pre-dating this generation is what you typically find in Catamarca - banded rhodo xls. The stuff that goes into cutting material usually. Pre-dating that is another thin (1-2mm) layer of bladed and/or botryoidal xls. Following that is another layer (1.0cm) of banded Rhodochrosite. Following this is a layer of what I would best describe as nearly crystalline xls. To top it off, there is a final layer of what I would best describe as another botryoidal layer. This is one cool rock indeed! No damage.
