Empressite is a mineral form of silver telluride AgTe.It is a rare grey orthorhombic mineral with which can form compact masses rarely as bipyrimidal crystals.Recent crystallographic analysis has confirmed that empressite is a distinct mineral with orthorhombic crystal structure different from the hexagonal Ag5-xTe3 with which empressite has been commonly confused in mineralogy literature.
