A few sharply terminated, well formed Manganite crystals emerge from a layer of Rhodochrosite. The Rhodochrosite is a peachy, pink/orange color and present as a thin layer of spherical aggregates. The Manganite crystals are jet black with a high luster. On the bottom of the specimen, there are micro crystals of dark red colored Andradite. There are also, very small, red colored crystals scattered across the surface of the Rhodochrosite. These are a very similar in color to the Andradite, but the habit does not look right. These crystals are really too small to make a visual identification, even under 10x magnification.

Condition: Very Good

Flaws: A few of the spherical aggregates of Rhodochrosite are incomplete.
