23" Purple, Cubic Fluorite Plate - Cave-in-Rock, Illinois
This is a massive, plate of lustrous, purple fluorite cubes on matrix from Harden County, Illinois. The entire plate is 23 inches wide and weighs 72 lbs. The largest cubic crystals on the plate are about 1" wide. The crystals by in large are in great shape with very little damage or abrasions. A gorgeous, cabinet sized display specimen from one of the most sought after Fluorite localities in the world.
Because of the size, this plate will ship in a custom wooden crate. Shipping within the US is included in the purchase price. International shipping is extra and will be billed after purchase. If you need an International shipping quote please contact us prior to purchase.
Archaeological discoveries near the Cave-In-Rock mining district of beads and other ornaments made of fluorite have placed the use of the stone to about 900 years ago when the land was inhabited by the Native Mississippian Americans. Early European settlers mining for galena in the 1830's discarded the fluorite as the lead they sought was more valuable at the time. In the 1880's it was discovered that fluorite was very useful in a new steel-furnace technology, and demand increased considerably, and several commercial fluorite mining companies appeared in Illinois/Kentucky region.

About Fluorite
Fluorite is a halide mineral comprised of calcium and fluorine, CaF2. The word fluorite is from the Latin fluo-, which means "to flow". In 1852 fluorite gave its name to the phenomenon known as fluorescence, or the property of fluorite to glow a different color depending upon the bandwidth of the ultraviolet light it is exposed to. Fluorite occurs commonly in cubic, octahedral, and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink, or black. Purples and greens tend to be the most common colors seen, and colorless, pink, and black are the rarest.
