La stichtita es un mineral de la clase de los minerales carbonatos y nitratos, y dentro de esta pertenece al llamado “grupo de la hidrotalquita”. Fue descubierta en 1910 en una mina de Tasmania (Australia), siendo nombrada así en honor de Robert C. Sticht, minero australiano. Un sinónimo poco usado es brugnatellita crómica.

Stichtite is a mineral, a carbonate of chromium and magnesium; formula Mg6Cr2CO3(OH)16·4H2O. Its colour ranges from pink through lilac to a rich purple colour. It is formed as an alteration product of chromite containing serpentine. It occurs in association with barbertonite (the hexagonal polymorph of Mg6Cr2CO3(OH)16·4H2O), chromite and antigorite. Discovered in 1910 on the west coast of Tasmania, Australia, it was first recognised by A.S. Wesley a former chief chemist with the Mount Lyell Mining and Railway Company, it was named after Robert Carl Sticht the manager of the mine.

Wesley a former chief chemist with the Mount Lyell Mining and Railway Company, it was named after Robert Carl Sticht the manager of the mine. It is observed in combination with green serpentine at Stichtite Hill near the Dundas Extended Mine, Dundas - east of Zeehan, as well as on the southern shore of Macquarie Harbour. It is exhibited in the West Coast Pioneers Museum in Zeehan. The only commercial mine for stichtite serpentine is located on Stichtite Hill. Stichtite has also been reported from the , Transvaal; Darwendale, Zimbabwe; near , Morocco; Cunningsburgh, the Shetland Islands of Scotland; Langban, Varmland, Sweden; the Altai Mountains, Russia; , Ontario and the Megantic, Quebec; Bahia, Brazil; and the Keonjhar district, Orissa, India. It is sometimes used as a gemstone.
