Celestine, Strontianite and Calcite, from the Stoneco Quarry, Lime City, Ohio
From the Stoneco Quarry, Lime City, Wood Co., Ohio, this is a beautiful Midwestern fluorescent specimen consisting of blocky, white celestine crystals , partially altered to strontianite, and small calcite scalenohedrons on a limestone matrix. This specimen shows a similar bright fluorescent response under all UV wavelengths, with the celestine and calcite showing bright blue/white fluorescence with a bright blue/green (short wave) and green (long wave) phosphorescence. The limestone matrix fluoresces a dimmer cream/yellow color, and provides a lovely contrasting background to the more brightly fluorescent minerals. The size of this specimen is 12 x 7 x 6 cm, and it weighs 242 grams.
