Orthoclase (Carlsbad twin from the original locality!)

Item Description

Classic and excellent Carlsbad-twinned Orthoclase from near the famous Type Locality, Karlovy Vary (Carlsbad). Complete all-around, the mottled, tan to gray crystal has the textbook, doubly-terminated form. Old-time material, the original Carlsbad twins were described from Karlovy Vary. This is an incredibly important specimen, for that reason! These pieces are part of a century-old Italian collection that was recently acquired. Its historic nature, aside from the sheer age of the specimens, is reflected in how dramatically geopolitical borders have changed since these labels were created. Bohemia has changed hands a few times, since!
