Quartz on Chalcedony (variety Youngite) Guernsey, Hartville District, Wyoming. Ex. Harold Dibble collection. From the early 1980s, this piece would have been a fantastic example for the find. Light purple in color, having a high luster, very three-dimensional, and damage free are all pluses for the piece. The specimen sits nicely on edge and views from any direction nicely. The piece has a couple very minor edge contacts as its only connection to surrounding rock. 8 x 7 x 4.5 cm overall. Far better in hand, especially what I would call the front view (seen in the first and last image). Very strong yellow green SW UV fluorescence. $200
