Bertrandite "eyes-chain" from Delta / USA.

Tiffany Stone (Bertrandite or Morado Opal) the usually purple colour and varied appearance make the stone very recognizable. The stone has a strong connection with higher energies, strengthens the foreboding, brings creativity into the mind, allows the wearer to interpret messages correctly, gives a clear connection with guides and shows the divine in oneself and others. Tiffany Stone is sometimes also called "Faceted Fluorite" and is clearly a combination of stones including Beryl, one of the lightest but energetically strongest active minerals. It is particularly rare and powerful. The gemstone is only found in Utah (U.S.A.). The mineral Bertrandite (Tiffany stone or Morado Opal) is a beryllium containing sorosilicate with the chemical formula Be4Si2O7 (OH) 2. Bertrandiet is a colourless to light yellow orthorombic mineral with a hardness on the Mohs scale of 6-7. It was first discovered near Nantes (France) in 1883 and was named after the French mineralogist Emile Bertrand. It is often found in beryllium-rich pegmatites. Bertrandite often occurs as a pseudomorphic beryl replacement. This mineral is, just like Beryl, a beryllium ore.
