My greatest mineral find while on my spectacular birthday trip: RARE Large Nodule of what is commonly called Tiffany Stone from Utah. Chances are you will never see anything like this amazing nodule pair ever again! This pair is for sale, message me for more information! “Tiffany stone" is a trade name used for a purple, blue and white gem material that can be cut and polished into beautiful beads, cabochons and tumbled stones. Geologically, Tiffany stone is a rock composed primarily of fluorite with smaller amounts of opal, calcite, dolomite, quartz, chalcedony, bertrandite and other materials. Other names used for Tiffany stone are "opalized fluorite," "ice cream stone," and "bertrandite." Tiffany stone is a rare material. It is mined at one location worldwide - the Brush Wellman beryllium mine, at Spor Mountain, western Utah. It occurs there as nodules that are part of the ore produced at the mine. The nodules typically contain between one and two percent beryllium by weight.

The United States Geological Survey reports that the nodules are carbonate clasts that have been largely replaced by fluorite. Small amounts of bertrandite, a beryllium mineral with a chemical composition of Be4Si2O7(OH)2, occurs as submicroscopic grains within the fluorite.

Almost all of the Tiffany stone mined at Spor Mountain is crushed and used to produce beryllium. A small amount has been carried out of the mine by employees, and a small amount has been gathered by collectors who have rarely been allowed into the mine. These are the only sources of the gem material because Brush Wellman has always been interested in producing beryllium and has not been interested in Tiffany stone. #tiffanystone #crystals #gems #geode #fluorite #bertrandite #icecreamopal #icecreamstone #utahminerals #utahrocks
