Tiffany Stone Cabochon
Tiffany Stone Cabochon
"Tiffany stone" is a trade name used for a rare purple, blue, orange, and white gem material that can be cut and polished. It is mined at one location worldwide - the Brush Wellman beryllium mine, at Spor Mountain, western Utah. Geologically, Tiffany stone is a rock composed primarily of fluorite with smaller amounts of opal, calcite, dolomite, quartz, chalcedony, bertrandite and other materials.
Freeform cut polished to a satiny luster. Flat, matte finish back with a beveled edge for ease of setting. You will receive the exact gemstone shown in photos.

^ Using the term “bertrandite” as the name of this material is incorrect. Bertrandite is itself a mineral and only comprises a few percent of the rock known as Tiffany stone.
* Using the term "opalite" to describe natural non-phenomenal (no play-of-color) common opal is deceptive and a punishable crime under US Federal Trade Commission regulations. Opalite is a man-made glass; it is neither synthetic opal nor natural opal.
