An excellent and showy, old-time English combination plate of glassy, light lavender, interpenetrating fluorite cubes richly covering limestone matrix and nicely accented by chalcopyrite-covered sphalerite crystals from the famed ore fields in Derbyshire. The chalcopyrite microcrystals have a nice, golden iridescence and are on both the sphalerite and fluorite. This old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe. Accompanied by an old German label. A pristine old-timer.
