Chalcanthite (ex Gary Weaver Collection)

Item Description

A beautiful specimen of glowing blue Chalcanthite on matrix from the Posey Mine in Utah. This is the first specimen that we've had to offer from this locality, and they are incredibly hard to find on the market. Upon close inspection, you can see the semi-fibrous form on the Chalcanthites, and they are rather gemmy up close. It should be noted that the label accompanying this piece states that it is associated with Phurcalite, a rare calcium uranium phosphate, which is a bright yellow color, but I cannot find a speck of it anywhere. From the collection of Gary Weaver (1944-2019), an electrical engineer who worked for Hughes Aircraft in California. After retiring to Prescott, Arizona in the early 2000s, Gary rekindled his childhood love of minerals, amassing a collection of roughly 2000 specimens, focusing on localities in which he and his wife had lived or visited (Mexico, Peru and the western / southwestern United States).
