Manjiroite and todorokite are RARE to uncommon hydrated manganese oxides. This exceptionally rich and showy specimen consists of bedded, dark gray, lamellar manjiroite altering to todorokite with really neat-looking vugs lined with glassy calcite crystals. Some of the lamellar manganese oxides are chatoyant! A nifty and unusual specimen from the Willy Israel Collection, who purchased this excellent piece from well-known dealer Clive Queit in 1986.
