Quartz ''cast'' after Fluorite (ex Gary Weaver Collection)

Item Description

This small cabinet specimen is a beautiful example of the famous old classic "casts" (some people call them epimorphs, but others use the term perimorph) of Quartz replacing Fluorite. The label accompanying this piece calls it a pseudomorph, but it's really more of a coating of drusy / sugary, white crystals Quartz that was deposited over the preexisting Fluorite, which later (for the most part) dissolved away leaving some hollow casts in the form of the original Fluorite octahedrons. The largest ''cast'' measures 2.5 cm. You can see that some of the Fluorite is still present on the underside of the piece, but areas on the reverse side show the hollow areas where it no longer remains. A fine piece of this classic material from southwestern Colorado. Valued at $850. From the collection of Gary Weaver of Prescott, Arizona (1944-2019). Gary was an electrical engineer who worked for many years 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).
