Hessite is a mineral form of disilver telluride (Ag 2 Te). It is a soft, dark grey telluride mineral which forms monoclinic crystals. It is named after Germain Henri Hess (1802–1850).

Hess was a student of Jons Jakob Berzelius. Above 155°C hessite is cubic, and on cooling below this temperature it develops fine phase transformation lamellae. As of 2021 there are now …
