Mineral Specimen - Fluorite crystals - Homestake Mine, Oatman Dist., Mohave Co., Arizona, USA - NearEarthExploration - Geology

3 1/4" x 2 1/4", 8.2cm x 5.7cm. Spectacular light lime-colored crystals of Fluorite, a Calcium Fluoride, from recent workings at the Homestake Mine in Arizona. The largest crystal measures a full 3/8", 10mm, on edge.

They are so clean and clear, that they are nearly invisible against the off-white Quartz matrix. An exceptional specimen for any collection of fine minerals! Note: The color is just a shade lighter than the picture shows - on my monitor, anyway -- differences in monitor settings may make the specimen seem slightly off color to the actual appearance.

Mineral Specimen - Pyrite 'Sun' - Sparta, Randolph County, Illinois - NearEarthExploration - Geology - www.nearearthexploration.etsy.com

2 7/8", 7.1cm. A gorgeous specimen! A splendid example of radiating Pyrite from the coal and shale beds of Illinois. This wonderfully unusual crystallization of Pyrite, a Sulfide of Iron, occurs only rarely in nature. These specimens are often referred to as 'Suns' or 'Dollars' because of their unusual shape. Traditionally, Pyrite forms Isometric crystals (Cubes, Octohedrons, or Pyritohedrons). The specimens from Sparta, Illinois, form radiating, flattened discs. To date, there is no consensus on how exactly these specimens were formed. One theory says that fluids rich in FeS2 flow down through cracks in the coal beds until the crack comes to an end, and the Pyrite slowly crystallizes in the horizontal seam between two beds. Another theory suggests that these are actually fossil remains of an unknown ancient creature, whose cast has been replaced over time by Pyrite. Regardless of depositional genesis, these Pyrite specimens are highly sought after by collectors of geological specimens. Specimen comes with stand and label, ready for your display.

They form perched on white Mordenite at this locale, and this specimen is a terrific example for both the species and the site. The Heulandite-Ca crystals are fully formed, completely terminated, and translucent. The Mordenite is snow white and forms a thick coating on the minor Basalt matrix (not visible on display).
