Hyaline Opal is present on the surface of this specimen ranging in color from clear to a deep, forest green. In places, the Hyaline has a reddish appearance, but actually, thie color is from the underlying matrix showing though completely clear Hyaline. The surface of the Hyaline has a bubbly habit and has a high glassy luster. This specimen is from the 2015 find and is quite notable for two reasons. First, it is one of the largest specimens found but more importantly is the color. The Hyaline on the vast majority of specimens ranged from nearly colorless to a light yellow to a light yellow/green. Only a few specimens were found with the very deep green color found on this specimen. Under SW UV, the Hyaline fluoreces a vivid green due to slight traces of uranium compounds.

Condition: Good

Flaws: There is one small area where the Hyaline is fractured (see the last picture prior to the UV pictures).
