TB14AJ2: A novelty at Tucson 2019. Shattuckite surfaces with two concentric generations, a first one felted and with a very intense deep color, and a second one botryoidal with a sky blue color. The first one is included in very bright Quartz crystals on a matrix partially coated by pale green Chrysocolla. As well as their beauty, we must note that, as a novelty, the presence of the well-crystallized Quartz at Milpillas is very rare.
We’ll send a copy of the analysis of the Shattuckite to the buyer.
The specimen has been photographed and published in the magazine ‘Paragénesis’, number 01/2019, page 78
