Tiffany Stone is a rare material composed of several different minerals. For this reason, it’s a rock, not a mineral. Tiffany Stone is a mineralized nodule found in just one location in the U.S.A., the Spor Mountain in Western Utah.

The nodules were once impregnated by groundwater rich in natural minerals. These impurities are the reason for the stone’s striking color. Tiffany Stone is composed of quartz, fluorite, dolomite, rhodonite, beryllium, and manganese oxides. The black color comes from impurities of manganese oxides, while white, yellow and pink come mainly from beryllium. Blue and purple come from fluorite.

Tiffany Stone is sometimes referred to as bertrandite, which is not correct. Bertrandite is a mineral in its own right but is present in Tiffany Stone. It’s a primary source of a highly sought-after chemical element called beryllium.  Most Tiffany stone is crushed to extract even the smallest amount of this sought-after metal. Tiffany Stone grades 4 on the Mohs scale of mineral hardness, which means it’s quite soft. It’s widely used for cabochons because of its striking color and markings.
