This excellent large cabinet-size fluorite specimen features glassy, complexly color-zoned crystals to ~5.5 cm on edge forming a large cluster in fine condition. The finely-detailed color zoning, with alternating bands of vibrant yellow, blue, and violet, is characteristic of the best fluorite specimens from the Minerva #1 mine. Minor black hydrocarbon inclusions on selective crystal faces contrast nicely with the intensely-colored corners and edges of the cubic crystals. A fine classic from a noted locality.
