Tiffany Stone is a beautiful and unusual gemstone that is found only in the mountains of Utah. It is also known as "Bertrandite", "Opalized Fluorite" or "Utah Lavender". It is mixture of different colors in swirls, plumes, dendrites and other interesting patterns. Tiffany Stone is composed of predominantly Opalized Fluorite in blues, purples and whites but is often mixed with other minerals such as quartz, chalcedony, dolomite, rhodonite, manganese oxides (blacks), and bertrandite (white, yellow or pink) that contains the mineral beryllium. Specimens with a lot of purple are generally the most sought after. The purple color comes from flourine gases.
Since it only comes from one area in the world, availability is very limited. And only a small percentage of rough material is hard enough and stable enough to cut into gemstones. Most all of the cut cabochons you might find are from old stock.
