SOLD Calcite with Siderite
stock #SOLD AX-22-279
Mancos Shale, Montrose, Montrose County
6.2 x 4.8 x 4.2 CM (cabinet)
Late Summer 2021
Well-defined Calcite rhomb crystals to 2.8CM across, on a contrasting Siderite matrix. The Siderite is botryoidal with a few isolated balls. In excellent condition as seen, the Calcite is fluorescent a good red color. Ex Frank Knaus and Dave Bunk, this is well above the usual quality for these Shale deposits, which we understand are either exhausted or off limits to collecting. A nice Colorado Calcite.
