Although there are about 10 crystals on this specimen, only 7 of them are undamaged, and of those, only 1 has a diameter greater than 3 mm. They all have a rosy-pink color, vitreous luster, and are generally transparent, with patches of cloudiness. The largest of these crystals measures 0.3 x 0.3 x 0.4"(8 x 8 x 10 mm) and lies at the very edge of the specimen. It is damaged and not quite complete, having suffered cleavage, and is quite cloudy, with small patches of transparence. The smallest crystal is about 2 mm in diameter and has a pale pink color. All of these crystals lay on a gray botryoidal crust that is likely related to psilomelane, or manganese "wad". The pink color of the shiny crystals makes a pretty contrast to the dull gray lumpiness of their bed. The base rock under the crust is layered, and probably contains manganese oxides and silicates and metallic sulfides.
