Mineral Specimen #6552 Tube Agate (Stalactic Chalcedony)
Flaming Gorge, Sweeetwater Co., Wyoming / Dagget Co., Utah
9.7 x 7.3 x 3.8 cm
3.8 x 2.9 x 1.5 in
Ex. A. Neely, 1960s
There were several Tube Agate specimens from Flaming Gorge in the stock from the Neely Rock Shop with this being by far the largest and best of the lot. The color of the Chalcedony varies from a slight violet tinted gray or a pastel yellow/orange on the tips of the tubes. There is a secondary deposit of low temperature Quartz with fluoresces green under SW. The location is likely now underwater since the completion of the Flaming Gorge dam in 1964. The dam, of the Green River, is 502 feet high and created a reservoir in the states of Wyoming and Utah which is over 90 miles long and is a now popular National Recreation Area used for boating.
Flaws: A few of the very ends of the tubes are incomplete but not noticable.
