9chmrl ((CALCITE pseudomorph after GLAUBERITE)), $10 MINIMUM BID, Camp Verde, Yavapai County, Arizona, 9.5 x 7 x 4 cm, Cabinet, | |
Excellent large specimen which is nearly completely undamaged. The small specimens are common and easily collected but these large specimens are much harder to collect and not nearly as common as the small ones. Glauberite is a sulfate and Calcite is a carbonate. If it dissolves in HCl, then it was a Calcite pseudo. |
