Item Description
Very fine example of the rare (certainly for Nchwaning) (Mn, Fe, Mg) hydrous silicate Neotocite (MINDAT: http://www.mindat.org/min-2879.html). The amorphous botryoids have superb luster and a pitch-black color. I looks very much like polished black obsidian. An interesting and attractive rarity.
