This specimen is composed of both complete and incomplete fluorite crystals have both yellow and blue regions. (Recall that fluorite color is dependent on light source. White LED illumination was used for the photos here, but the color might be a bit different in your mineral cabinet, especially if you use fluorescent or halogen lights.) Lustrous, deep brown sphalerite is also present, as well as patches of china white, amorphous barite. A classic Cave-in-Rock combination specimen, probably from the Minerva No. 1 Mine.
