A highly mineralized Keokuk, Iowa area geode pair that contains a very light brown/grey chalcedony lining. Upon the chalcedony are two separate calcite growths - one of these was cleaved when the geode was opened. The other is undamaged and safely down in the cavity. There is also a speckling of slightly bigger than micro pyrite crystals on the chalcedony - these are slightly larger than the typical Keokuk geode but they can come larger. There are also two sphalerite crystals - one was cleaved when the geode was opened but the other is found in the bottom of the half. Nice combination geode that is more of a reference versus collection specimen given the damage. Collected in Hancock County, Illinois. Price is $30.00 plus shipping.
