Quartz ''casts'' after Fluorite on Quartz

Item Description

A rarely seen specimen from the Snowflake #2 Claim in the San Juan Mountains of Colorado. This cabinet sized specimen hosts attractive ''casts'' (epimorphs/perimorphs) of white Quartz which have completely replaced cuboctahedral crystals of Fluorite, sitting on white milky Quartz matrix. A few of the ''casts'' are broken, but this is actually beneficial as you can see they are completely hollow inside, so they are truly ''casts'' retaining the original shape of the Fluorites that have since been dissolved away. A rare locality piece to be sure, which would make a great addition to any Quartz collection, a Colorado mineral collection or a suite of ''casts''.
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).

The piece was collected by Robert Stoufer in 2017.
