Fluorite

specimen number:
2063101

location:
Stoneco White Rock Quarry, Clay Center, Allen, Ottawa Co., Ohio, USA

description:
A beautiful miniature of this Ohio classic. Two interconnecting brilliantly lustrous translucent root beer brown cubic crystals of fluorite with very minimal attached Celestine. This is complete all around and in great condition. Brightly fluorescent under longwave ultraviolet light. This one is really sweet and of much higher quality than most for specimens from this locality is in this size range. The specimen comes with two previous labels, one from the collection of Ray DeMark and one from the collection of Michigan Technological University, Seaman Mineral Museum. The latter label notes that this was collected in the 1940s and at one time was part of the collection of Donald Gabriel.

The Stoneco White Rock Quarry located in Clay Center, Allen Township, Ottawa County, Ohio, operates within Paleozoic sedimentary strata, specifically mining Silurian and Devonian dolostones and limestones for commercial aggregate and construction materials. Historically, active commercial quarrying operations have intersected vugs and cavities within the carbonate rock matrix that house world class mineral specimens. Mineral collectors and museums highly prize the site for its exceptional specimens of distinctive brown root beer fluorite, bladed blue celestite, and associated calcite crystals, making it a legendary locality in midwestern mineralogy.
