Gemstone Cabochons B - D

Bertrandite / Tiffany Stone

Bertrandite or Tiffany Stone is composed of many minerals, that vary from sample to sample. It is rare, because it comes from an area in the west desert of Utah where beryllium is mined and is crushed during the mining process. The name bertrandite is misleading as it is not the major mineral in the stone. The name tiffany stone came from the patterns in the stone resembling tiffany glass. It is an opalized stone that forms in nodules, composed mostly of opalized fluorite with other minerals such as quartz, chalcedony, dolomite, rhodonite, manganese oxides, bertrandite, beryl, opal, and others. Most commonly patterned in purple, blue, white and black it is an unusual and beautiful gemstone.
