This specimen features sharp, golden nail head calcite crystals from the historic Tri-State mining district of Missouri, Kansas, and Oklahoma. The distinctive flattened crystal habit gives the appearance of “nail heads,” a signature form from this region. Under ultraviolet light, the calcite fluoresces, adding an extra dimension to its natural beauty. A fine example of classic Tri-State mineralogy and vintage American mining heritage.
