Gypsum pseudomorph after
Glauberite - $15 Camp Verde, Camp Verde District, Yavapai County, Arizona 4.5 x 1.8 x 1.2 cm (1.8 x 0.7 x 0.5 inches) Specimen status: Available Click here to order The Camp Verde locality has long been
famous for pseudomorphs after glauberite. Among these, calcite
pseudomorphs are (in my experience) significantly more common than
gypsum pseudomorphs. Here we have a sharp and complete gypsum
pseudomorph, with a frosted surface and transparent interior. The only
reason this undamaged specimen is not three times the price is because
I was able to obtain quite a few at a very reasonable price.
