5.1" Purple Fluorite on Sparkling Dolomite - Elmwood Mine

This is a 5.1" wide specimen that contains beautiful purple fluorite crystals on a sparkling dolomite matrix from the famous Elmwood mine in Tennessee. The largest cube is .45" wide. It comes with an acrylic display stand.

The Elmwood Mine is a zinc mine in Carthage, Tennessee that opened in 1969. It then closed for many years, only to be reopened in 2010. It has produced many world class specimens of fluorite, calcite, barite, and galena over the years. Specimens used to be plentiful as miners were allowed to recover specimens, but collecting is strictly prohibited by the new mine owners. They've gone to great lengths to prevent the mining of specimens, including blasting crystal pockets or filling them with slurry.


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.

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate (CaMg(CO3)2).

The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. It does not rapidly dissolve in dilute hydrochloric acid as calcite does. Crystal twinning is common.

Dolomite was first described by Carl Linnaeus in 1768, and in 1791 it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu. He first recognized the material in buildings of the old city of Rome, and later as samples collected in the mountains known as the Dolomite Alps of northern Italy.
