Fluorite on Quartz ''casts'' after Calcite (ex Gary Weaver Collection)

Item Description

A rarely seen specimen from the La Fluorita Dulcita Claim in south-central Arizona. This locality is best known for it's beautiful purple "ochsenaugen" (ox eye) habit crystals, but this piece is different and harder to find on the market in my experience. The piece is rather sculptural and three-dimensional due to the fact that it started as a group of scalenohedral Calcite crystals which were coated by Quartz and later dissolved away leaving "casts" (some people call these either epimorphs or perimorphs), but the most attractive aspect of the piece is that a later generation of gemmy purple octahedral Fluorite crystals came in and covered the Quartz on both sides of the piece. The piece is crystallized all over, and only minor roughness can be see where it was detached from the pocket wall when it was collected. The largest Fluorite crystal measures 4 mm across. A must have specimen for any fan of worldwide Fluorites, unusual "casts" / pseudomorphs or minerals from Arizona. 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).
