Description:
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 (shortwave) and green (longwave) phosphorescence. The limestone matrix fluoresces a dimmer cream/yellow color and provides a lovely contrasting background to the more brightly fluorescent minerals.
