Description :

exceptional 25-piece vintage North American mineral and rock specimen collection represents a classic mid-20th-century field-collector's assemblage. Assembled primarily during the 1940s and 1950s, the lot includes a highly desirable, postmarked provenance slip dated October 4, 1952 (Spokane, Wash.), verifying its historical timeline.

The collection stands out for its well-preserved, hand-written and typed vintage paper labels detailing specific, historically significant mining districts, geological formations, and precise chemical compositions across the United States, Canada, and Mexico

The collection is beautifully diverse, spanning rare secondary ore minerals, classic crystalline structures, volcanic materials, and ornamental silicates:

Rare & Secondary Ore Minerals: Features exceptional specimens of deep-blue Linarite paired with greenish-blue Caledonite (Riverside Co., CA); a rare specimen of Pseudobrookite (Fe₂TiO₅) embedded in volcanic Rhyolite; and a brilliant spray of bladed zinc silicate Hemimorphite from the world-class El Potosí Mine in Chihuahua, Mexico.

Classic North American Copper & Iron Localities: Includes multi-mineral copper ores showing vibrant green Malachite, deep blue Chrysocolla, and iridescent Bornite from Furnace Creek (Death Valley, CA)and Arizona. Iron mineralogy is highlighted by dense Hematite from Boulder, CO, and metamorphic Greenalite from the historic Biwabik formation in the Mesabi Iron Range, MN.

Crystalline & Structural Display Pieces: Notable display pieces include a rich, deep purple cubic Fluorite heavily intergrown with a crystalline Calcite cluster from the famous Crittenden Springs Fluorspar District, KY; a highly textured, coralloid "bubbly" Aragonite from Blue Lake, FL; and dark Hedenbergite/Diopside pyroxene fibers from the Golconda Mine, ID.

Volcanic Glass & Ornamental Stones: Features glassy, sharp-edged volcanic Obsidian from the premier Glass Buttes, OR rockhounding locality; a fragment of fine-grained Alabaster from Falkland, B.C.; Scapolite (Wernerite) from Quebec; and a vibrant, smooth piece of Blood Agate from Cisco, Utah
