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). Hessite is found in the US in Eagle County, Colorado and in Calaveras County, California and in …

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 …
